Hi all,

Thanks again for prompt replies.

To be honest, due to time factor I couldn't try the patches.

But the latest?? 8.22.5 Linux driver from ATI works fine
with 2.6.15.2.

Except for the follwoing error---in /var/log/Xorg.0.log
(II) fglrx(0): Kernel Module Version Information:
(II) fglrx(0):     Name: radeon
(II) fglrx(0):     Version: 1.19.0
(II) fglrx(0):     Date: 20050911
(II) fglrx(0):     Desc: ATI Radeon
(WW) fglrx(0): Kernel Module version does *not* match driver.
(EE) fglrx(0): incompatible kernel module detected - HW accelerated
OpenGL will not work
(II) fglrx(0): [drm] removed 1 reserved context for kernel
(II) fglrx(0): [drm] unmapping 8192 bytes of SAREA 0xe0ae5000 at 0xb7a55000
(WW) fglrx(0): ***********************************************

But since I don't use my laptop for plaing games, I can live with it.

Kind Regards and happy hacking,
