Wrong CPU Speed

A few years back when people were starting to run UT on their laptops, there
was an issue with speedstep and UT would run either hafl speed or double
speed once the chip loaded and speed step kicked in.

I have a similar problem, but a little bit different.  I'm running an
overclocked Quad and I have lowered my multiplier so as to run my buses
wider.  Windows does not understand a lower multi, so it reports the wrong
clock speed.  My 24/7 overclock is 8X400 for 3.2 Ghz.  Windows assumes I am
using the stock multi for 9X400 that would be 3.6 Ghz.  Apparently, UT gets
the clock speed from Windows and not from the chip.  My UT Log says

(here is the important part)

Init: CPU Speed=3600.168976 MHz
Init: CPU Page size=4096, Processors=4
Init: CPU Detected: PentiumPro-class processor (GenuineIntel)

When in fact, I am running 400 mhz lower.  -  I've been having a few odd
issues playing online and I'm more or less convinced it has to do with this.
 My chip is capable of 9X400 and then some, but I've never cared to push any
of my rigs harder then necessary for 24/7 use.  I'm not planning on running
this system beyond 3.2 ghz day in day out.  -  I could run at 9X356 for
3.2ghz, but I like my buses wider.

Was there a permanent fix for the laptops besides turning off speedstep?  Is
there a way to tell UT my clock speed manually rather than allowing Windows
to lie to it?
