- Delayed commit of code for the ASUS A7M motherboard

- VIA 686 cleanups from the A7M code (it now works in a different pci slot).
- Update of assembly printing routines to use the debug levels:
  TTYS0_TX_CHAR now becomes CONSOLE_<LEVEL>_TX_CHAR.
  It's more verbose but now the controls are the same as with the C code.
- Break off of loglevel.h from printk.h.  loglevel.h is safe for both
  the assembly routines and the C code to include.
- Next round of commits for the supermicro p4dc6
- SMP setup updates (Rons board is broken)
  I now allow the other SMP processors to report their existence.
  I really need to add a minimum time to run but that hasn't happened yet.
- SMP per motherboard table of apicids, as the assumption that they
  would always be 0 & 1 with only two cpus fails.
- RDRAM setup updates.  The code isn't done but it now works on more
  than one board at a time.
- More cacheram work.  Minor bug fixes and some macros to use it from C.
- Entry point changes so we no longer have to jump over our gdt.
- Added/Audited the cpufixup for the i786
- IDE intialization for the 82801 ich2 chip.
