Subjectautoprobing of sound submodules

Here is my relevent kerneld setup.

alias char-major-14-1 adlib_card

alias char-major-14-sequencer awe_wave
post-install awe_wave strace /usr/bin/sfxload /sndbnk/synthgm.sbk 1>/root/strace.log 2>&1
#pre-install awe_wave modprobe -k adlib_card

(Sorry for line wrap, if it does.)

I modified sound_open to issue a request_module for the device being opened.
Then, in the ioctl for the sequencer device, I issue a request for
char-major-14-sequencer. All works find if I modprobe awe_wave.

If, however, I run drvmidi with no modules loaded, sound loads, then
adlib_card. drvmidi opens /dev/sequencer, issues an ioctl, and then awe_wave
attempts to load. When sfxload tries to run, it also attempts to open
/dev/sequencer. This fails, has drvmidi already has it open. Hence, sfxload
doesn't install the sound font, and drvmidi exits.

Does anyone have any pointers on this? Maybe I should make a new function
that can load a sound font without using an ioctl.
