Heads up - /proc/kcore May Be Going Away

Noticed this on kernel traffic shortly after noting that the description
of extracting Video BIOS in the ADLO paper uses /dev/kcore. I take it
that there'd be no problem in creating a more specialised architecture
specific device for extracting things like parts of the BIOS.

No problem, we have /dev/mem. I use this command to extract video bios.

$ sudo dd if=/dev/mem of=/tmp/vgabios bs=65536 skip=12 count=1
