Since it's quite much debugging info, I uploaded it to
http://bwalle.de/tmp/debugoutput-unmodified
Basically it's
set VGA mode 12
set VGA mode 3
VBE mode info request: 100
VBE mode info request: 101
...
VBE mode info request: 6a
set VGA mode 3
VBE mode info request: 100

It doesn't change the result (that it doesn't work). It only makes the
kernel failing much faster and of course there's much more debugging
output: http://bwalle.de/tmp/debugoutput (250k).
