Well, there are two parts:
Is the sound card supported by the software?
Is the hardware quality of the sound card sufficient for the recording

I have no experience with your audio card. However, I would guess that
the input quality of the card might be the bottleneck. Input quality is
worse than output quality for most 'consumer' cards.

I thought you already tested the sound card, but just the quality was
not good (enough). Did I misunderstand something?

It seems you have alsa installed. What is the output of 'aplay -l'?

The recommended sound system on linux is alsa, nowadays. The command
lists the sound cards available for alsa.

Thinking of it, do you have the right mixing levels set? Those are set
by 'alsamixer'.

Finally, is there any particular reason you run 'sarge' instead of
current 'lenny'? Sarge has been obsoleted by 'etch', which has been
obsoleted by 'lenny' some while ago. My memory already fades of how I
used my audio card in those 'sarge' times ;-)
