line about protected mode is  "vesafb: protected mode interface info
at c000:5a83", does it mean the protected mode is avaliable?

I put this options: 
kernel          /boot/vmlinuz-2.6.11-1-686 root=/dev/hda6 ro acpi=off
video=vesafb:ypan,mtrr,vtotal:64,vremap:32 vga=786

The related message in /var/log/dmesg :
vesafb: framebuffer at 0xd0000000, mapped to 0xe0880000, using 1800k,
total 65472k
It seems to find all video memory, but it still uses only 1800k
instead of 32000k as I put in the vremap option, and my program still
crashes when I try to use page flipping. Do you know why? Is there
something wrong with my options?

Thank you very much,
Regards, Carlos
