FC6 & fglrx kernel module compatibility?

[pcharles]

Using the new driver v.8.33.6 (and older versions 8.31.5 and 8.32.5), I'm unable to build the fglrx kernel module compatible with FC6.

RPM's for FC6 seem to build successfully using:
./ati-driver-installer-8.33.6-x86.x86_64.run --buildpkg Fedora/FC6

Produces a set of RPM's which install without errors.

ATI driver works, graphics look good on a dual-headed DVI system, but the kernel module fails to load, with the error:
Jan 23 13:14:44 kernel: fglrx: Unknown symbol flush_tlb_page

As a result, DRI isn't available:
[drm] failed to load kernel module "fglrx"
(WW) fglrx(0): Failed to open DRM connection
...
(WW) fglrx(0): No DRM connection for driver fglrx.
...
(EE) fglrx(0): GART is not initialized, disabling DRI
(WW) fglrx(0): ***********************************************
(WW) fglrx(0): * DRI initialization failed! *
(WW) fglrx(0): * (maybe driver kernel module missing or bad) *
(WW) fglrx(0): * 2D acceleraton available (MMIO) *
(WW) fglrx(0): * no 3D acceleration available *
(WW) fglrx(0): ********************************************* *
[drm] failed to load kernel module "fglrx"

Kernel is 2.6.19-1.2895.fc6xen on x86_64. Adapter is ATI x1300.

I had the same problem with earlier kernel updates. Struggled with the problem using several different kernels. Even modified the fglrx sources to try and work around calls to flush_tlb_page. Managed to produce a module which loaded without error, but still couldn't get DRI to work.

Thought I'd take another shot with the new driver release from ATI, on the latest kernel update available for FC6. Thanks for any pointers.
