Default Re: [260.19.0x Geforce 310M] Cannot read VAIO EDID (both with and without CustomEDID)

I filed a bug about CustomEDID using mmap(), and we'll change it back to read() in a future release.
Hi, I generated bug reports over ssh as you suggested. Also I generated bug report for working driver 256.53.

And this is very interesting (from kernel dmesg):
ioremap error for 0x9e000-0x9f000, requested 0x10, got 0x0
