Bug on atyfb

Hi,

I'm trying to use atyfb on 2.6.10-rc3, but I'm getting a kernel oops just at 
modprobe time. By tracking the problem, it seems that 'pll_limits.xclk' is 
the heart of the problem, as seen in line 2210 from atyfb_base.c:

par->xclk_per = 1000000/par->pll_limits.xclk;

It happens that pll_limits.xclk is zero, because of an attribution made on 
line 3246:

par->pll_limits.xclk = pll_block.XCLK_max_freq/100;

pll_block.XCLK_max_freq, in this case, is read from BIOS a few lines above (at 
line 3229, to be more precise), and the value being returned from this copy 
here is 20. So we have a problem, since the result from 20/100 = 0 will be 
used as denominator to set par->xclk_per's value.

Since I didn't know what clock was being expected by the driver, I couldn't go 
any longer. If some of you has time and can give a look on it, I'm sending 
some information about my card, as well as ksymoops results and .config.

Thanks,
Lucas
