x86, setup (2.6.30-stable) fix 80x34 and 80x60 console modes
Note: this is not in upstream since upstream is not affected due to the
new "BIOS glovebox" subsystem.
As coded, most INT10 calls in video-vga.c allow the compiler to assume
EAX remains unchanged across them, which is not always the case. This
triggers an optimisation issue that causes vga_set_vertical_end() to be
called with an incorrect number of scanlines. Fix this by beefing up
the asm constraints on these calls.
