Garbled text screen since upgrade to kernel 2.6.18-3-686

[Peter Hillier-Brook <phb@hbsys.plus.com>]

Since the recent upgrade to the above referenced kernel my initial, text 
mode start-up screen consists of an interesting arrangement of random 
pixels! It's fine in grub, but once Linux starts up everything goes 
random (well pseudo anyway) until 'X' starts, after which all is well.

Dropping back to kernel 2.6.17-2-686 and all is visually well, 
eliminating a hardware problem.

On another machine, identical except for the graphics card, the same 
monitor, via a KVM switch, works fine.

Any thoughts, anyone??
