discussions about hacking this particular model's firmware have been
going on for quite some time. here's one source for reading and further
information:

http://www.broadbandreports.com/forum/remark,9070712~mode=flat~days=9999

be sure to go to the root of the linksys forum there for additional
threads on the subject. some useful info in there and folks willing to
help. found some info for a problem i'm having with an 802.11b router
i've got here. google you'll find a bunch more.

if you're not personally writing all the code you're sticking in your
router, you are introducing a security risk into the very network you're
trying to protect. just keep that in mind :)

you might be better off with the flexibility your linux box is giving
you. if you want wireless connectivity on top of what you have, just
setup an access point behind the router you've got now.
