After looking at OverDrive code it looks like this is PP table issue of my GPU
VBIOS as it doesnt have OD range and so it cant find it thus only underclocking
is allowed. Hardcoding the range in the kernel is surely a huge hack but indeed
works and im able to overclock the card.
It would be useful to have an kernel argument that we can pass trough GRUB that
would just disable this check as some laptops dont have this table.
