Here is something I was playing with. It saves the hardware registers
once only during the driver's pre-init phase, and doesn't restore them
until VT swtich.

The normal driver init sequence has an additional hardware restore step,
which brings the card back to its lit up console state before switching
off again and programming graphics setup. This patch drops the extra
restore, which seems to work in my case at least.
