Thanks.  It correctly detects panel size from BIOS, unfortunately it behaves 
like X.org driver (which is probably expected).  I captured video just in case 
it provides some clue to somebody 
(http://platan.vc.cvut.cz/ftp/private/radeon/video.avi).  Otherwise I'll try 
some trial & error session during weekend.
