This does indeed happen on IBM ThinkPad's (at least on the 770 series with the Trident
Cyber chipsets). The problem is the
VGA server that is used and its settings clash with the LCD screens capabilities
resulting in a black screen or just a total mess.
Using a kernel with SVGA framebuffer support and a framebuffer X server would actually
be a solution for these machines, as the
SVGA framebuffer works perfectly on the IBM ThinkPad's (well at least it does on the
600 and 770 series, as those are the
models I have tried it with), including high colour depth and high resolutions.
My vote would be for using a kernel with SVGA framebuffer support and the framebuffer
X server, but then I don't have any
machine to worry about with an ATI videocard (as from what I understand the ATI cards
have problems with the SVGA
framebuffer).
