Your problem seems to be, not with your friends computer but rather the way
you are setting up the mode. Your code is designed for VESA1.2 and I find
anything above 8bit colour doesn't tend to work.

To use VESA2.0 add 0x4000 to the mode number, this makes VESA2.0 use the
linear frame buffer. However, you will have to write some mode detection
routines to get the linear frame buffers address
and wil have to map it to linear memory ( or it will be split up into 64k
chunks which can be a pain ).

Get the official VBE2.0 specs from http://www.scitechsoft.com/ which will
guide you better than me.

NOTE: you need to know a fair bit on using the transfer buffer ( __tb ) and
how to map physical memory into linear memory.
