SiS550 SoC Support Committed

[Ollie Lho]

Ron,
        I just committed a bunch of code for SiS 550 SoC support. I made a
lot of changes to solve Pentium v.s. Pentium Pro incompability. The
current
code in CVS should works fine for both SiS 630+Celeron and SiS 550.
Please
check it out to see if I had made any mistake. 

        There is a new #ifdef IOPAIC stuff in hardwaremain.c which
I have no idea how to do it correctly.
