PS2 keyboard doesn't work properly in default VirtualBox environment

There's probably an issue with the ps2 crate and how its initialization routine works.

Relevant log excerpts:

[I] kernel/ps2/src/lib.rs:101: first ps2 port test pass!!!
[I] kernel/ps2/src/lib.rs:114: first ps2 port interrupt enabled

with this line being the key:
