Why don't you fix your BIOS rather than GRUB? It is quite
easy for BIOS to ignore int 0x10.

Summary: [PATCH] Add an option to disable any video output
Original Submission: There were suspicions that the bootloader's int 0x10 BIOS
video output can prevent the system from booting. The following patch disables
any video output which is not controlled by menu.lst.
In order to completely disable video output, one should specify a serial port
in the GRUB's menu.lst as a default terminal.
There are 2 drawbacks not solved by this patch:
a) The video BIOS int 0x10 is still required after applying this patch. A
better patch should intercept any int 0x10 and emulate sane default responses.
b) The Linux kernel will display the "Uncompressing image..." message through
the video BIOS call.
