 It's just been compiled:
ftp://ppc.linux.or.jp/pub/users/oikawa/Xserver/hw/xfree68/XF68_FBDev-19990801-glibc2.1.gz

 Because FB_ACCEL code isn't defined for C&T 65550 and it requires to accesss
both MMIO and IO space, it scans PCI configuration space through /proc/bus/pci.
I'm not quite sure if it can detect C&T 6555x properly (just write and compile,
not checked, yet). I hope Geert or someone accept the patch...
