And action on a newer kernel works when you add options at boot > nomodeset. And below I attach the info file from the kernel boot.msg version > 2.6.37.6 and 2.6.39.1. IIRC, openSUSE sets i2c-algo-bit.bit_test=1 by default which causes the radeon i2c init to fail since the radeon i2c buses require pre/post i2c setup to work properly which the i2c subsystem didn't handle by default. You can either set i2c-algo-bit.bit_test=0 on the kernel command line in grub, or make sure your kernel has this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d3b3e15da14ded61c9654db05863b04a2435f4cc See this bug for reference: https://bugs.freedesktop.org/show_bug.cgi?id=36221 Alex > > 2.6.37.6: > <6>[ Â Â2.833968] [drm] Initialized drm 1.1.0 20060810 > <6>[ Â Â2.906448] [drm] radeon defaulting to kernel modesetting. > <6>[ Â Â2.906453] [drm] radeon kernel modesetting enabled. > <7>[ Â Â2.906520] checking generic (d0000000 1000000) vs hw (d0000000 > 8000000) > <3>[ Â Â2.906523] fb: conflicting fb hw usage radeondrmfb vs VESA VGA -
