Thanks, Alex, <br>
<br>
I think that's what I was looking for:<br>
<b><tt>radeon_accelfuncs.c: OUT_ACCEL_REG(RADEON_DEFAULT_OFFSET,
info->dst_pitch_offset);</tt></b><br>
<br>
I'll try it in a few minutes.<br>
<br>
I wrote a little test program to see what RADEONSetPitch() does with
1400 and it<br>
does indeed round virtualX up to a displayWidth of 1408,
RADEONPreInitModes,<br>
however, sets displayWidth = virtualX without adjustment, which was
confusing.<br>
I was having trouble figuring out what the driver did with
displayWidth. <br>

The driver handles all modes just fine. see radeon_driver.c
<br>
RADEONSetPitch() and the drawing engine's destination/pitch register:
<br>
info->dst_pitch_offset = (((pScrn->displayWidth *
<br>
info->CurrentLayout.pixel_bytes / 64)
<br>
<< 22) | ((info->fbLocation + pScrn->fbOffset) >>
10));
