Something I found that was similar was that the Motherboard's Power 
control (Sleep mode) plus the Sleep mode on my monitor plus the sleep 
mode on my KVM switch plus the sleep mode on W98 and/or Linux was 
incompatible.  My monitor would sleep and never wake up.  When I moved 
the KVM to a Linux box which I turned OFF all Power saving #$#@ my 
monitor would sync after I turned off and on the monitor again.  If I 
changed it to either my other Linux box (with Power saving on) or W98 
even after a reset of the monitor, It wouldn't sync.

I basically just turn off the Motherboards Power control off.  Also if I 
remember right that was a fix for W98SE to many Motherboards/BIOS fixes.
