- I have added at the end of "uc_ovl_init_layer" the following lines:

        VIA_OUT( ucdrv->hwregs, 0x288, 0x00001c00 );
I have added them also, and the colors are correct, but too bright when 
compared with the older cle266 chipset.

I searched for some documentation on the hardware registers, and found 
the following: 
<http://sourceforge.net/docman/display_doc.php?docid=23693&group_id=102048>. 

And also in via_video.h, I found the following:
typedef struct{
        ...
        unsigned long video1_CSC1;           /* 284 */
        unsigned long video1_CSC2;           /* 288 */
        ...
} video_via_regs;
I don't know which registers are they related to in the documentation. 
What I want to know is whether I can tune the above two registers to 
make the output dimmer.

Any ideas?
