Si, en la version 5 se paso a VxWorks ( bastante comun en los cable modems y routers ).
Se puede flashear, pero para ello necesitaras un jtag, y refashearlo con el dd.wrt
wiki.dd-wrt.com/wiki/index.php?title=Fla…ion_5_WRT54G
De momento es la unica manera de hacerlo de una manera "sin riesgos"
Se puede hacer sin jtag, pero el metodo es un poco peligroso...Si falla la corriente durante el proceso, entonces, de manera impepinable, necesitaras el jtag para recuperarlo.
Aqui tienes la explicacion de como hacerlo sin jtag.

Aqui, como se hace el cable jtag ( por si no te funciona el metodo vxworkskiller )

For the WRT54G v5, v5.1, and v6 ONLY:
The risks (PLEASE READ)
1. If something goes wrong during the flash, like a power outage in the couple of seconds it takes to flash the CFE, your unit will be bricked, recoverable only by JTAG. This risk is small, but real.
2. If you don't follow instructions here, or don't read warnings, you are in for a world of bricked routers.
1. Download [vxworks_prep_v03.zip] and extract.
2. Download [vxworks_killer_g_v06.zip] and extract, OR create a custom firmware image with your MAC address embedded in it. See the 'Changing your MAC address' section below for more information.
3. Download [DD-WRT micro generic]. You may want to check [DD-WRT] to make sure there isn't a newer version than v23 SP1. Do not use the one labelled 'WRT54G' or 'WRT54GS', use the 'generic' version.
4. If you don't know how to use (or don't have) a console mode TFTP tool (i.e. tftp.exe), download the [Linksys TFTP transfer tool].
5. You will want to assign your network adaptor a manual IP address, since you may loose your automatically configured one and have trouble TFTP'ing the firmware. To do this see the troubleshooting section or google it. It's done at the properties dialog of your network connection, in the 'Internet Protocol (TCP/IP)' properties.
6. Go to your router's web based interface and enter the 'Administration' tab. Then select 'Firmware Upgrade' and choose the vxworks_prep_v03.bin file. Hit apply. After a minute, your browser window will go blank. At this point, power cycle your router.
7. Again point your web browser (preferrably Internet Explorer, other may not work in this step) to http://192.168.1.1. You'll see a different sort of firmware upgrade screen. This is the Management Mode. Select and apply the vxworks_killer_g_v06.bin firmware upgrade. WAIT for your browser window to turn to report 'Success'.
8. Now unplug the power cord of your router, then plug it back in. The power LED should now be blinking.
9. TFTP transfer DD-WRT micro generic (re: not mini) to your router, whose IP will be 192.168.1.1, or 192.168.1.245 if you used an older vxworks_killer. There are two ways to do the TFTP transfer. One is using Linksys's TFTP Windows program, which you may have downloaded in step 3, the other is at the console/terminal:
* Console tool: Example: TFTP -i 192.168.1.1 PUT dd-wrt.v23_micro_generic.bin
* GUI tool: Simply enter the router's IP address, select the DD-WRT micro generic image, then initiate the transfer. The password field can be left blank. Don't unplug your router when it finishes (see below).
10. Do NOT reboot your router after TFTP'ing, this will happen automatically. It takes a couple minutes after the TFTP transfer finishes for the firmware to actually be flashed.
B. Make sure you use 'binary mode' instead of the default 'ascii mode' in the TFTP transfer utility. In the Windows console mode tool the switch is "-i".
