* on. This is the one comparable to the 300 series.
* 2. VRAM queue mode (bit 6, 0x40). In this case, one will
* have to do queue management himself. Register 0x85c4 will
* hold the location of the next free queue slot, 0x85c8
* is the "queue read pointer" whose way of working is
* unknown to me. Anyway, this mode would require a
* translation of the MMIO commands to some kind of
* 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"
* SR26 bit 0 resets the queue
* Size of queue memory is encoded in bits 3:2 like this:
* 00 (0x00) 512K
* 01 (0x04) 1M
* 10 (0x08) 2M
* 11 (0x0C) 4M
* The queue location is to be written to 0x85C0.
