[edit] 2.6.x Kernel and Xorg

I have been trying to get Xorg to run on my Ultra10/Cerator3D with kernel 2.6.x (13,14.3,15rc), but this far I haven't managed due different reasons, the prebuilt one in the package CD didn't find any drivers for the keybord (even under 2.4), tried with the new modular one and this time I got problem with that Xorg didn't find the sunffb (had only built sunffb and vga driver) and reverted back to the monolitich Xorg (6.8.2-r4 with xaa patch), this lead to that the machine locked, still able to ssh to it (running 'ps' resulting in a hard crash). Xorg.0.log just stop in the middle, no error messages, did upgrade to 6.8.2-r6 still the same thing. Got the bright idea to run a dmesg and got the following: 

program X is using MAP_PRIVATE, PROT_WRITE mmap of VM_RESERVED memory, which is deprecated. Please  
report this to linux-kernel@vger.kernel.org kernel BUG at arch/sparc64/mm/generic.c:68!

This is the error message from kernel 2.6.15-rc1, but it's kind the same in 2.6.13-r5.

With the 6.8.2-r6 and kernel 2.4 I got the Creator3D to output, the glxgear test gives a bit less than what I get on a PegasosII with a ATI Radeon 7000.
