to-do list for hp700 port:

- do a pkg bulk build
- gdb
- CD boot?  (if the current install image doesn't work there too)
- fix PCI drivers (see driver-status list)
- kernel profiling (needs newer gcc)
- teach ddb stack trace how to go through trap frames
- teach ddb stack trace about unwind info (so it works in optimized kernels)
- X support
- HIL bus support
- additional CPU support:
       PCX-T (PA 7200) support
       PA-8xxx in 32-bit mode
       PA 7000
- MULTIPROCESSOR
- hppa64
- fix FP emulation code
- COMPAT_HPUX
- COMPAT_LINUX
- EISA and ISA drivers

eventually:
- better fix for booting from disk
  - why does xxboot cause PDC_COPROC to fail?
  - find the bug with cache-flushing


done:
- sysinst-based install image
- turn on -O2 for kernel builds
