OK, this is the email I meant to send this monring before I pushed the send button at the wrong time.
I've been doing a number of experiements this morning to look into this a bit further. Basic results say that ati-drivers will build on gentoo-sources (both 2.6.13 and 2.6.14) but will not build on any of the -rt variants I've tried so far. There is no performance advantage to using the ATI drivers on PCI Express cards as DRI doesn't work yet. OK, so I've tried: 2.6.13-gentoo-r5 + ati-drivers-8.14.13-r2 - works: [EMAIL PROTECTED] ~ $ glxgears Xlib: extension "XFree86-DRI" missing on display ":0.0". 2793 frames in 5.0 seconds = 558.600 FPS 3360 frames in 5.0 seconds = 672.000 FPS 2.6.14-gentoo + ati-drivers-8.14.13-r2 builds but won't modprobe. From dmesg: fglrx: Unknown symbol verify_area fglrx: Unknown symbol register_ioctl32_conversion fglrx: Unknown symbol unregister_ioctl32_conversion 2.6.14-gentoo + ati-drivers-8.18.8-r1 - works: [EMAIL PROTECTED] ~ $ glxgears Xlib: extension "XFree86-DRI" missing on display ":0.0". 3388 frames in 5.0 seconds = 677.600 FPS 3538 frames in 5.0 seconds = 707.600 FPS So, down to here there is the ability to build the ATI drivers but no acceleration as DRI is not working for PCI Express cards yet. Note that the results above are the same when usign the radeon driver from the kernel or no driver at all. 2.6.14-rt6 + ati-drivers-8.14.13-r2 - won't build.
