You should never listen to Zick. 53c710 is always part of Lasi on PA
machines. There's a discrete 53c700 on pre-Lasi machines. There is
never a 53c710 behind Dino. Dino has a serial port, a ps/2 port, and a
pci host bridge.

Wrong. sg list management is used by PCI devices behind Dino as well as
by GSC devices.
