I managed to add Gravis Ultrasound support to System Shock 1 a couple of days back and tested it. Here's what I did:
Get Ultrasound drivers: http://www.dosgames.com/forum/about10574.html
Unzip it and use the ULTRASND411 file (Rename it to ULTRASND and put it in C:/)
Then, when inside the RES folder go to the dosbox.conf in either the dosbox folder or gulikoza and look for:

Code:
[gus]
#      gus: Enable the Gravis Ultrasound emulation.
#  gusrate: Sample rate of Ultrasound emulation.
#           Possible values: 22050, 44100, 48000, 32000, 16000, 11025, 8000, 49716.
#  gusbase: The IO base address of the Gravis Ultrasound.
#           Possible values: 240, 220, 260, 280, 2a0, 2c0, 2e0, 300.
#   gusirq: The IRQ number of the Gravis Ultrasound.
#           Possible values: 5, 3, 7, 9, 10, 11, 12.
#   gusdma: The DMA channel of the Gravis Ultrasound.
#           Possible values: 3, 0, 1, 5, 6, 7.
# ultradir: Path to Ultrasound directory. In this directory
#           there should be a MIDI directory that contains
#           the patch files for GUS playback. Patch sets used
#           with Timidity should work fine.

gus=true
gusbase=240
gusirq=5
gusdma=3
ultradir=C:\ULTRASND
Make sure your Dosbox.conf folder matches this.

Get the AIL30 Driver: http://www.scene.org/file.php?file=%2Fmirrors%2Fscenesp.org%2Fcompilations%2Fblastersound_bbs%2FGUS%2FGAIL3214.ZIP&fileinfo
unzip it and look for: ULTRA.DIG and ULTRA.MDI (Rename ULTRA.dig to SB16.DIG and ULTRA.MDI to MPU401.MDI
go into RES then click sound.
Put those files into sound (make sure you back up the old ones.)

Open up dosbox.conf again.

Code:
[autoexec]
# Lines in this section will be run at startup.
mount C:/
mount S ..
S:
cdshock.exe
exit

Make sure your autoexec matches this one or music won't work. Also, make sure you copy RES into C: as well, or there will be no sound.

Hope you benefit from this.

It's very cool that you wrote down how to get it work, just noting here that SS1 always had support for Gravis Ultrasound. 

By the by, you got over your arachnophobia? How come?

SS1 didn't have support for Gravis Ultrasound. LGS was planning on releasing a patch that added support, but it never saw the light of day.

Off Topic: I got over it by turning that mod off and facing them, suddenly they aren't so scary. I still run from the bigger ones though, lol.

You're right. I went by the fact that Gravis Ultrasound files exist in the game. Well done.

Hmm. Seems there's something wrong with the science deck. Once a sound plays (any sound) the music stops. Only way to fix that is to exit the game and start it back up again. I'll look for a fix and update this thread when done.
