I added lines that were in modules.conf to modprobe.conf.
Now and mpu401 driven devices is active!
The USB still is not, though snd-usb-audio is registering on boot and 
deregistering on shutdown.

Both are listed in lsmod, similar to listing in 2.4.22:

# lsmod | grep mpu401
snd_mpu401              4224  0
snd_mpu401_uart         8352  2 snd_mpu401,snd_es1968
snd_rawmidi            25536  2 snd_usb_audio,snd_mpu401_uart
snd                    55012  10 
snd_mixer_oss,snd_mpu401,snd_usb_audio,snd_es19                      
68,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device

# lsmod | grep usb
snd_usb_audio          63968  0
usbcore               114652  1 snd_usb_audio
snd_pcm               104640  2 snd_usb_audio,snd_es1968
snd_rawmidi            25536  2 snd_usb_audio,snd_mpu401_uart
snd                    55012  10 
snd_mixer_oss,snd_mpu401,snd_usb_audio,snd_es19                      
68,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device

# lsmod | grep es1968
snd_es1968             34020  0
snd_ac97_codec         55556  1 snd_es1968
snd_pcm               104640  2 snd_usb_audio,snd_es1968
snd_page_alloc         12100  2 snd_es1968,snd_pcm
snd_mpu401_uart         8352  2 snd_mpu401,snd_es1968
snd                    55012  10 
snd_mixer_oss,snd_mpu401,snd_usb_audio,snd_es1968,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device

The snd-es1968 and snd_ac97_codec are similarly listed, even though this card 
is also not active (the card has a AGOPO chip but different codecand there is 
presently no ALSA driver for it).

Only the mpu401 is listed in cat /proc/asound/cards. Both the mpu401 and the 
USB interface worked in 2.4.22.
