Hi,
On a Clevo laptop with a Radeon Mobility M7 LW (AGP), enabling
the Radeon frame buffer results in an unusable LCD display (as
if the horizontal and/or vertical sync were incorrect -- lots
of skewed diagonal lines)
The kernel log shows this:
radeonfb_pci_register BEGIN
radeonfb: ref_clk=2700, ref_div=12, xclk=16600 from BIOS
radeonfb: probed DDR SGRAM 65536k videoram

ppll_div_3 = 0x10060
ron = 1792, roff = 22036
vclk_freq = 10800, per = 787
Console: switching to colour frame buffer device 175x65
With FBDEV disabled in X, I see this in Xfree86.0.log:
(WW) RADEON(0): LCD: Using default hsync range of 28.00-33.00kHz
(WW) RADEON(0): LCD: using default vrefresh range of 43.00-72.00Hz
(II) RADEON(0): Clock range: 12.00 to 350.00 MHz
...
(**) RADEON(0): *Mode "1400x1050": 108.0 MHz (scaled from 0.0 MHz), 64.0 kHz, 60.2 Hz
(II) RADEON(0): Modeline "1400x1050" 108.00 1400 34208 34320 1688 1050 1050 1053 1063
try the attatched patch (its against test4).

The patch fixes the text-mode console, but X still cannot use the
frame buffer (the display with UseFB is skewed, and something appears
to go wrong so that all disc activity stops, and the keyboard stops
responding -- as if interrupts were disabled)

Thanks, this patch makes the frame buffer usable on my computer. I
suggest you send it to Linus.
