Isn't there a severe restriction of the length of IDE-cables? At
least for UDMA?

Yes, it's a Gravis Ultrasound PnP ISA Soundcard. These are the
options I use:
options snd-card-interwave snd_index=1 snd_id=CARD_1 snd_port=0x220 snd_irq=11
s nd_dma1=5 snd_dma1_size=128 snd_dma2=6 snd_dma2_size=128 snd_midi=0
~$ cat /proc/dma
4: cascade
5: GFA1/CS4231 record
6: CS4231 playback
~$ cat /proc/interrupts

I'll do this as a last resort but downloading 20MB+ is quite a big job
for my modem.

I've searched news and the web already. Today I found a message of
someone who seems to have had a similar problem. I'll wait for his
answer before I'll waste even more time searching for the reason.
BTW I tried setting the kernel parameters `hda=slow hdb=slow'. And
now the sound works flawlessly even when accessing a cd! PPP still
doesn't work properly, though (At least _some_ packets come through
but still ~80% are lost).
