I suppose I should look for kernel document to see how to get the radeon
module loaded and what available parameters are there (so that it
doesn't try to probe the second VGA card). But I didn't find anything
mentioning the radeon kernel module in kernel documents:
http://www.kernel.org/doc/Documentation/fb/

Although I do find pretty much documents about other non-ATI card's
modules like sis, s3, matrox.
