more info of "my player" http://rtd1261.wikidot.com/ is a rtd1261. Is
running a kernel 2.6.12-VENUS which a kernel modified by Realteak it
self, I think. 
Some of support for realtek wireless has been add to main kernel much
more later, so I have a little hope , with a newer kernel I can have
support for "my player". rtd1261 also have busybox as OS. 
So seems, at this point, is not so hard put there a new kernel :) .

but kernel-vanilla-2.6.35-85.fc13.src.rpm , can't be compile to mipsel
arch ? 
What I need ? 
With buildroot , I can build many apps (on fedora13) that work in the
box, but boot a new kernel, I still have some doubts.
