SubjectRe: Generic VESA framebuffer driver and Video card BOOT?

BTW, does this look like right way to POST VGA BIOS from real mode? It
is what we currently use... and it works on some machines...

movw $0xb800, %ax
movw %ax,%fs
movw $0x0e00 + 'L', %fs:(0x10)

cli
cld

# setup data segment
movw %cs, %ax
movw %ax, %ds # Make ds:0 point to wakeup_start
movw %ax, %ss
mov $(wakeup_stack - wakeup_code), %sp # Private stack is needed for ASUS board
movw $0x0e00 + 'S', %fs:(0x12)

pushl $0 # Kill any dangerous flags
popfl

movl real_magic - wakeup_code, %eax
cmpl $0x12345678, %eax
jne bogus_real_magic

testl $1, video_flags - wakeup_code
jz 1f
lcall $0xc000,$3
movw %cs, %ax
movw %ax, %ds # Bios might have played with that
movw %ax, %ss
