ah ok, small changes.. actually the latest git allows for multi platform compilations.. so I'll just add the changes to makefile as 'palmpre' target.
about adding that include sound/driver.. i don't think that's necessary... actually those 'sound' includes were a mistake (bad copy/paste :p) and they're removed in the latest git...
I won't add that, so just make sure you get the latest git, and type 'make palmpre' to see if it works.
Also, the KDIR path shouldn't be like that.. I made a mistake committing the path with /home/kakaroto and I fixed it yesterday iirc, now it should be a common path for the kernel, so it would for anybody... it's standard for the kernel sources to be in /usr/src to I'll make it /usr/src/linux-2.6.24 (instead of /home/blaze/ps3/linux-2.6.24). So make sure you move your kernel directory to /usr/src before trying it.
