xdga colors problem

[Tamas K Papp <tpapp@Princeton.EDU>]

When I use xdga (fullscreen), the colors are weird, eg the blue is
replaced by cyan and the whole thing looks psychedelic.  Is this a
known problem, and is there a workaround?  I am using a 15" Albook
(2004),

% uname -a
Linux tpapp.student.princeton.edu 2.6.10-powerpc #1 Wed Feb 23 20:43:26 CET 2005 ppcGNU/Linux
% dpkg -l xserver-xfree86
ii  xserver-xfree86 4.3.0.dfsg.1-10 the XFree86 X server

Thanks,

Tamas
