I have the same floppy drive. On current(yesterday's), when
booting with ACPI, I get the following message:

fdc0: I/O to control range incorrect

But when booting without ACPI, I get:

fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> at port 0x3f7,0x3f0-0x3f5 irq 6 drq 2 on isa0
fdc0: FIFO enabled, 8 bytes threshold
fd0: <1440-KB 3.5" drive> on fdc0 drive 0

So I can mount it with no problem.

This problem exists definitely from 5.2 release, maybe earlier.

Full dmesg with ACPI enabled is at:
http://homepage.eircom.net/~sarunas/dmesg/dmesg_with_acpi

Verbose dmesg with ACPI enabled: 
http://homepage.eircom.net/~sarunas/dmesg/dmesg_with_acpi_verbose

dmesg with no ACPI:
http://homepage.eircom.net/~sarunas/dmesg/dmesg_no_acpi

Verbose dmesg with no ACPI:
