Re: [radeonhd] firegl V5200: radeonhd or radeon driver?

Hi folks,
I've also got a FireGL 5200 (in a Thinkpad T60p). It's been a lot of
fun to work with the developers and watch support radeonhd grow over the
past year. At one point radeon had better support (redhat and ATI
worked together to quickly patch support into the older driver), but
that work has been integrated into the radeonhd driver since, which is
designed from the ground up for these newer chips.
A word of warning to Fedora users though - the new overly graphical boot
sequence in the recently released F10 brings up the system with frame
buffers initialized. Radeonhd's acceleration works best with EXA turned
on, which can't start if the framebuffer is already active, resulting in
awful performance.
The workaround is to turn off the switch to fb by adding the kernel
parameter "nomodeset" to the boot options. I'm not sure how radeonhd
can protect itself against the card being initialized into the wrong
mode.
