[PATCH] tridentfb: Fix scrolling artifacts during disk IO
Reported by: Jochen Hein (Bugzilla Bug 4312)
When there is disk I/O happening, the framebuffer has a little snow on
the screen. Once I/O has finished, no garbage remains on screen.
This bug was explained by: Knut Petersen
Most important is CRTC register 2f, signal quality is also improved for
higher vclk values by changing set_vclk() according to the X drivers and
cyblafb.c
The fix is to set the performance register (0x2f) with a more stable
value.
