Yes, this might be the case, but I wouldn't worry about that right now. 
As far as I remember we haven't encountered any real PowerPC or SPARC 
machine with a different default configuration than 8 bpp and that's the 
reason why the code for such cases (15 bpp, 16 bpp, etc.) in HelenOS is 
not properly debugged. This can be fixed easily later on by using the 
correct VISUAL_RGB_5_6_5_BE for 16 bpp.

Anyway, we know now what are the issues and where. Thanks everybody for 
the cooperation!
