* accelerator assembly and writing these commands
* to the memory location pointed to by 0x85c4.
* We will not use this, as nobody knows how this
* "assembly" works, and as it would require a complete
* re-write of the accelerator code.
* 3. AGP queue mode (bit 7, 0x80). Works as 2., but keeps the
* queue in AGP memory space.
*
* SR26 bit 4 is called "Bypass H/W queue".
* SR26 bit 1 is called "Enable Command Queue Auto Correction"

* Size of queue memory is encoded in bits 3:2 like this:
