Subject: XF68_FBDev patch: TrueColor fixed
Hi !
Got XF68_FBDev working with TrueColor (16+32 bpp) on i386 today. Tested
with vesafb and kgicon. Patch below, glibc binary at
http://user.cs.tu-berlin.de/~kraxel/linux/#fb
Attention: compiler problems continue: gcc 2.7.2.3 FAILED to build a
working binary, I used egcs-1.0.2 to build the Server.
