Exclamation Kernel's 2.4.{27,28} Frame Buffer Overheats Graphics cards!

Kernel's 2.4.{27,28} Frame Buffer Overheats Graphics cards!

After using Linux under 2 very different systems, I found that the Frame Buffer causes the graphics cards to overheat, and possibly damage my cards.

System 1
System: IBM Thinkpad A31.
Processor: Intel Pentium 4 mobility 1.6Ghz
Graphics Card: 32-mb ATI Radeon 7500
Kernels Tested: 2.4.27, 2.4.28
Tested Frame Buffer options: (both modulated and built in) for Radeon/ATI and standard VGA
Results: always caused blue lines to appear everywhere; When this happened I also noticed Higher Frame Rates from glxgears (40% Increase in speed..)

IBM Thinkpad is now currently in unusable condition.

System 2
System: Custom Built, Motherboard = Soyo K7V Dragon Plus!
Processor: AMD K6-2 1600+ XP
Graphics Card: 64-mb Nvidia GeForce 3 Ti 200
Kernels Tested: 2.4.28
Tested Frame Buffer options: (both modulated and built in) for GeForce (riva..?) and standard VGA
Results: always caused blue lines to appear everywhere; Problem continues until i shut down system for a few minutes to cool off. When Under GeForce (riva?), Frame Buffer doesn't fit screen properly (expanded, but not fit to monitor), causing numerous lines to become unsee-able.

At first I thought it was Simply my 2+ year old Notebook was simply getting old..
But after I began installing Linux on my second computer The same exact problems appeared.

It is apparent that the Frame Buffer is mis-clocking my graphics cards, causing them to overclock and possibly become damaged.

How do I fix this?
How do I configure Frame Buffer settings? (if possible)
What possibly mis-configured kernel settings would cause this?
Please Help as soon as possible, I am forced to use Windows for now for the safety of my Graphics cards!! And I am already down 1 computer!
