You could try changing the "index" parameters in the options lines
in /etc/modprobe.conf. Those determine the order in which the modules
are loaded. The entries would read as:

-------
alias eth0 3c59x
alias snd-card-1 snd-intel8x0
options snd-card-1 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 1 >/dev/null 2>&1
|| : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias snd-card-0 snd-emu10k1
options snd-card-0 index=1
options snd-emu10k1 index=1
remove snd-emu10k1 { /usr/sbin/alsactl store 0 >/dev/null 2>&1
|| : ; }; /sbin/modprobe -r --ignore-remove snd-emu10k1
alias snd-card-2 snd-mpu401
options snd-card-2 index=2
options snd-mpu401 index=2
remove snd-mpu401 { /usr/sbin/alsactl store 2 >/dev/null 2>&1
|| : ; }; /sbin/modprobe -r --ignore-remove snd-mpu401
--------

(the remove lines are being wrapped by the email client, that and the
following line is just one). 

After changing modprobe.conf do a "/sbin/depmod -a" and restart alsa. If
you have /etc/rc.d/init.d/alsasound you can use it (but you should
logout and do it from a text console, otherwise all audio apps will
quit), or just reboot.
