Via82cxx chipset problem

I tried this question on another list and was told not to try to change my
mhz speed because I would corrupt my hard drive possibly. But does this
mean I am actually running at only 33mhz.? This doesn't seem like a viable
way to run my computer and I am having problems with installing new memory
that may be related to this. My original message is below; any help would
be appreciated.
Thanks.

try here first.
I have a via82c597 rev 4 chipset and an Award bios. I have anabled the
via82cxxx support in my kernel, but perhaps I do not understand what
numbers to put in on the command line, or for which ide to put them in,
because no matter what I do a 33mhz bus speed is assumed; if I try putting
66 even in I get something about this being impossible.
I have included part of my dmesg here, and have included enough so you can
see my setup and a couple of other messages that puzzle me.
Any help would be appreciated.
