This is not exactly true. I have updated the ALSA sound card matrix.

I (an ALSA developer) have received a Audigy 2 ZS Notebook PCMCIA card 
from Creative for the purposes or writing a drive for Linux.
I have run up against a bug in the Linux kernel PCMCIA code that I 
cannot fix. So effectively, until the PCMCIA code is fixed, the ALSA 
development cannot start.
Unfortunately, the PCMCIA standards are not open and free, so I also 
cannot provide any sensible suggestions on how to fix the PCMCIA code.

If you are interested, the bug is in regard of the PCMCIA Cardbus 
section of the kernel involved in assigning IOPORT resources to the PCI bus.
In effect, although the Audigy 2 NZ Notebook appears in "lspci", and it 
contains valid IOPORT resources, if the driver code makes an "outb()" 
instruction to any address in the IOPORT range, the PC hangs.
