The VGA_2X_MODE bit apparently affects the display even when the VGA
plane is disabled. The bit will set by the BIOS when the panel width
is at least 1280 pixels. So by preserving the bit from the BIOS we
end up with corrupted display on machines with such high res panels.
I only have 1024x768 panels on my gen2 machines so never ran into
this problem.
The original reason for preserving the VGACNTR register was to make
my 830 survive S3 with acpi_sleep=s3_bios option. However after
further 830 fixes that option is no longer needed to make S3 work
and preserving VGACNTR doesn't seem to be necessary without it,
so we can just revert the entire patch.
