Ah, according to the README file in the driver directory:
7. Known Limitations
- No 32bpp support in this driver.
- Running Two Xservers on different VT's is not supported at this time.

The operations you listed are two entirely different blitter instructions
(SRC_COPY_BLT as opposed to COLOR_BLT). You're correct in that the code
to stuff the instruction into the ring buffer is very similar, but in the
first case (SRC_COPY_BLT), the 5th parameter is a 14 bit source pitch,
while in the second case (COLOR_BLT), the 5th parameter is a 24 bit color.

For the SRC_COPY_BLT, the correct code would be:
OUT_RING( pI810->BR[13] & 0x3FFF );
i.e. masking the value to 14 bits instead of 16. Matt had said this
probaly isn't a big deal, though.
