The aliases are generated from device and id lists in the relevant
source file during the kernel build process.

in your case that would be:
  {USB_DEVICE(0x0ac8, 0x305b), DVNM("Z-star Vimicro zc0305b")},
in
  drivers/media/video/gspca/zc3xx.c

That id is in that file since it's creation somewhere between 2.6.26
and 2.6.27_r1.

Are you sure, you have a recent udev and it's properly configured?
