Extreme slow video memory in 4.3.0 on tdfx
Hello!
I have a Voodoo 3 2000 AGP using 4.3.0-pre1v1 on a 2.6.0-test4 kernel.
While getting issues with tvtime straight (http://tvtime.sf.net)
extreme slowiness of my video memory has been noticed.

Alas I cannot tell if this was the case under 4.2.1, but I've tested
it with 2.4.22 kernel version - the same effect. The same card on
2.4.18 and XFree86 4.1 shows much better results:

Did I miss some configuration option? What can be the reason? Direct
Rendering is enabled according to glxinfo.
Thank you.
