* Merge Andrea's priotree fix.
* Add a debug configuration to i386. It's currently still disabled, but
I verified it compiles. Some notes:
- Config is based on bigsmp
- I turned on ACPI debugging; it can be configured at runtime, so this
is a no-brainer IMHO
- I turned on debugging for some filesystems. Subject to debate ...
- I turned all the hack support options on except for
KDB modules which don't compile.
