355cs vs 755cs screen vomit?

[jesse@spine.com]

Greets,

I have a 755cs, and I run chicogo beta on it.  My mom just got a 355cs, and
it has some trouble with the video.  During both the win31 standard install
and chicago install, I've gotten screen vomit, more specifically, those
familiar vertical colored bars that obliterate the screen.

I thought that they used the same video in both boxes?

I sent one back and got a new one already, but it has the same trouble, which
seems odd to me, since it's happening in the standard vga mode, with and
without the vesa driver.

Any help appreciated!
