Hi all,

SMSC SLC90E66 is southbridge chip, designed to be almost exact clone of
Intel PIIX4. So it needs same handling as an original chip.

Attached two patches against 2.4.5-ac17,=20
first adds IRQ router support (using functions for Intel PIIX4),
second adds quirk handling (ACPI/SMBus resources) same as for original PIIX=
4.

Both patches are untested, written according to SLC90E66 datasheet.

Best regards.
