Attached is a diff for your ASL. Apply it with patch and then recompile
the new asl:
iasl -f lanny.asl
Then install the backup DSDT:
cp DSDT.aml /boot
Add this to loader.conf:
acpi_dsdt_load="YES"
acpi_dsdt_name="/boot/DSDT.aml"
Reboot and your floppy drive should be detected. I'm ccing -current in
case others have problems with a non-working floppy drive with ACPI.
The key to look for is a line in dmesg like this:
fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> port
0x3f7,0x3f4-0x3f5,0x3f2-0x3f3,0x3f0-0x3f1 irq 6 drq 2 on acpi0
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Note the range of ports should read 0x3f7,0x3f0-0x3f5 on a working system.
