Sound will currently not work for Linux binaries (this is documented in
the compat_linux manual page). It will be at some point in the future,
but it won't be in 1.1. The Linux (voxware) sound drivers have a different
interface.

I suppose you do have pcvt compiled into the kernel? I would guess so,
otherwise you won't get to this point. Are you sure the binary has
no setuid bits that take the root permissions away from you again?

Also, SVGAlib tries to open /dev/mem to mmap() video memory. This will
fail if you are running in secure mode; you might have to recompile
your kernel with the INSECURE option.
