-/* CR44 takes values 0 (head A), 3 (head B) and 4 (heads tied)
- * it affects only the 8 bit vga io regs, which we access using mmio at
- * 0xc{0,2}3c*, 0x60{1,3}3*, and 0x68{1,3}3d*
- * in general, the set value of cr44 does not matter: reg access works as
- * expected and values can be set for the appropriate head by using a 0x2000
- * offset as required
- * however:
- * a) pre nv40, the head B range of PRMVIO regs at 0xc23c* was not exposed and
- * cr44 must be set to 0 or 3 for accessing values on the correct head
- * through the common 0xc03c* addresses
- * b) in tied mode (4) head B is programmed to the values set on head A, and
- * access using the head B addresses can have strange results, ergo we leave
- * tied mode in init once we know to what cr44 should be restored on exit
- *
- * the owner parameter is slightly abused:
- * 0 and 1 are treated as head values and so the set value is (owner * 3)
- * other values are treated as literal values to set
