- Fix wrong userland fsbase load after gdt move that caused qemu to
segfault sometimes on first invocation
- Get rid of redundant & in two places
- Bump PORTREVISION
There still is the unresolved issue of (likely) the gdt move causing the
host to hang for one guy, if this happens to you you can try the following
kernel patch that sets up seperate gdts at boot so kqemu doesn't have to
do the move:

Thanx to: Yamagi for testing
