No, the snd_mpu401 and snd_mpu401_uart drivers are included with JAD.
Yes, that's the way to go. Here, for a CreativeLabs Audigy2, the
snd_mpu401_uart module gets loaded automatically at boot, maybe there's an
option for your onboard soundchip driver to tell it to load/use the MIDI
driver? Maybe the YaST sound configuration offers this already (look in
"Advanced Setup" for the driver options list), otherwise the ALSA Wiki has
pages with descriptions of each driver's setup, including the module options.
Ah and by the way, on openSUSE/JAD any local additions for /etc/modprobe.conf
should be put into the file /etc/modprobe.d/sound.
Another thing to consider: There's two types of joystick-MIDI cables around,
"active" and passive". Creative invented this cut-down MIDI interface where
part of the interface is put into the cable to keep card prices low. I don't
know if this applies to onboard serial ports, I for one bought the wrong
(passive) cable after getting bad advice from the computer dealer, and it
took me weeks or even months to figure this out - only MIDI in (or -out, can't
remember now), was working.

Yes.

IMO they should work together.
