problem with Mach64 on FC5

Hi, I have Mach64 chipset and FC5; I compile the libdrm and module for
2.6.17-2187 kernel. I compiled only libdrm and drm module,
not Mesa.
Compilation finish succesfully, but when I restart xorg, I
have this error on the kernel output:

[drm:mach64_dma_init] *ERROR* mach64_dma_init called without lock held,
held  0 owner 00000000 c74358e0 [drm:drm_unlock] *ERROR* Process 3216
using kernel context 0

and this:

(II) ATI(0): [drm] SAREA 2200+1208: 3408
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)

(II) ATI(0): [drm] removed 1 reserved context for kernel
(II) ATI(0): [drm] unmapping 8192 bytes of SAREA 0xd0975000 at

in the Xorg's log.

Can I modify the version from 2.0.0 to 2.0? Is possible? How I do?I try
to watch the source code but I don't find any infos. 

My lspci -v information about Videocard is:
