+ * 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:
