Subject description: Trying to get Softlink AMR to function, OK with 2.11

I would be grateful for advice on the best approach to getting 2.17 to load the correct modules for my AMR. Various other threads seem relevant to the problems I've had since 2.12 in getting the trident module to drive the soundcard without causing the integrated Softlink modem to malfunction, specifically failing to detect the dial-tone.

I recall a much earlier thread that suggested ensuring that Soundblaster entries in modprobe.conf should be suppressed, and that the following lines should be appended.

alias snd-card-0 snd-trident
alias sound-slot-0 snd-trident
alias snd-card-1 snd-intel8x0m
alias sound-slot-1 snd-intel8x0m

I have found this approach less troublesome than running the Alsa wizard, especially when the modem wizard was not run until after a reboot with modprobe.conf already edited. This worked OK up until
2.16, but with 2.17 the modules are assigned at boot. In my case slamr is assigned to the sound card, and PcTel to the modem, at least according to Pupscan.

Many combinations of blacklisting have been attempted, but to no avail. I either have a functioning modem, or sound, but not both.

I have a suspicion that these observations are relevant to a number of other threads involving integrated sound cards.

OK, so Soup was off. Here's the Meat. System is Athlon. Board is Micro ATX size and has single Audio Modem Riser slot for a special audio/modem riser card (type of winmodem).
Manufacturer is PCTel, 1039:7013. A backup Connexant HCF-type winmodem, 14f1:1085 is also installed but disabled (at least in XP). Puppy's modem wizard does not recognise the AMR as a PCTel, but as a SoftLink modem. Not that I'm complaining about that - the connection created is the best by miles of any Linux distro I have tried. Still using 2.11 daily with no problems.

Here is the PCI report from PupScan (for 2.17 live CD with hard drive save):-

VENDOR: 1039 DEVICE: 0730 KERNEL MODULE: unknown

VENDOR: 1039 DEVICE: 5513 KERNEL MODULE: unknown

Note that the slamr module is registered to the Audio Accelerator, not to the Modem Controller. The PCTel module is reported there.
