Clock slowdown (was: Can't run MOL on Titanium...)

This box indeed has a PowerLogix G3 upgrade card. I only have used 
9.1 on it (everything was fine with 8.6 except that file sharing made 
MOL very unstable and I had to go to 9 to fix it).

Fair enough, but I'm reading between the lines that you know of no workaround.

What's odd is that *one* time MOL started up without the clock 
slowdown, and I remember that during that one time while MOL was 
booting I was pinging the MOL IP address. I left it [running fine] 
for maybe 60 days because I was afraid to lose it. When I finally had 
to reboot the machine for other reasons, I tried all kinds of things 
at MOL boot like pinging the IP but I was never able to reproduce the 
one success. I doubt this is useful info, but I thought I'd relate it 
anyway.

Thanks for your efforts Samuel. Glad to see your presence again.
