after i recompiled my (new) kernel with a new config i don't have 3d-acceleration support anymore.
glxgears shows about 200 fps. befor i had 2000 fps!
the problem is i can't load the radeon module from the dri-project anymore.
i have done a "emerge xfree-drm" after the kernel-compilation.
but a "modprobe radeon" shows:
<snip>
/lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o: unresolved symbol cmpxchg
/lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o: insmod /lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o failed
/lib/modules/2.4.20-gentoo-r5/kernel/drivers/char/drm/radeon.o: insmod radeon failed
</snip>
what is that about "unresolved symbol cmpxchg"? because while rebuilding the xfree-drm this error occured:
<snip>

did anybody expirience the same? or what did i wrong?
