Re: MSI 6712 KT4AV asl/dsdt acpi + floppy hack (No floppy with ACPI on 5.3-BETA2)

MSI MS-6758 875P Neo + ACPI with FBSD-5.3-Beta3 SESNAP 09/04/2004 and
FBSD-6.0-CURRENT SESNAP 09/04/2004 is still unable to use FDC0 with ACPI
enabled:

fdc0: <floppy disk controller> port 0x3f7, 0x3f4-0x3f5, 0x3fs-0x3f3 irq 6 drq 2 on acpi0
[FBSD-6.0] fdc0: does not respond
[FBSD-5.3] fdc0: cmd 3 failed at out byte 1 of 3
device_attach: fdc0 attach returned 6

Disabling ACPI allows the floppy controller to be "properly" determined and set up.
Running without ACPI is not a problem for me since I don't have a laptop and have no
need for "power controls". No modifications to DSDT were made.
