Mine is 0x00801028.

I did it and really the kernel system does not hang anymore but ...

I wasn't able to find any kernel configuration that would allow me to
actually use the device.
I've tried everything sensible (IMHO), ie:
device pcm
device pcm0 at isa? port 0x530 irq 5 drq 0 flags 0x11
(the card should be detected as MSS compatible, right)
device pcm0 at isa? port 0x530 irq 10 drq 0 flags 0x11
(the probe says that the card uses irq 10 - as a matter of fact all PCI
devices on my machine except for IDE controllers and built-in WinModem
use this irq)
device pcm0 at isa? port 0x3c0 irq 10 drq 0 flags 0x0
(this exactly matches resources that Windows claim this device is using)
device pcm0 at isa> port ? irq 10 drq 1 flags 0x0
(per some older advice found in freebsd-questions archive = another attempt
on MSS compatibility mode)
None of the above works. The system never detects any pcm device. Using
boot -v I wasn't able to find anything that would give me a clue what is
wrong. In all isa? cases I see somthing like:
mss_probe: no address given, try 0x530
mss_detect, busy still set (0xff)
pcm0 failed to probe at port 0x530-0x537 irq 10 drq 1 on isa0
I have another datapoint; OSS 3.9.3s for FreeBNSD 4.x works for this card
and cat /dev/sndstat says:
OSS/FreeBSD 3.9.3s (C) 4Front Technologies 1996-2000

Anyway, thank you for helping,
Martin.
