Change Kernel in Ubuntu Lucid
After installing lucid alpha 2 and enable xorg-edgers, radeon OSS is working great! i have kms and dri2 and i am runing some opengl test now. WOW!! great progress.
But what i cant understand is that if i change the kernel from 188.8.131.52 (lucid a2 default) to 2.6.33.rc4 my screen turns black, ubuntu doesn't boot.
I tried 3 workarounds without success:
1) Edit /etc/initramfs-tools/modules and add radeon. Run update-initramfs -k all -u
2) Add R600_rlc.bin and R700_rlc.bin to /lib/firmware/radeon/ and to /lib/firmware/2.6.33-020633rc4-generic/radeon/
3) Edit /etc/modprobe.d/radeon.conf and add options radeon modeset=1
