there is no "cardbus side" of the driver.

a cardbus device appears to an ALSA driver (and i suspect to the
kernel as well) as a completely regular PCI device. unless you go
"fishing" for evidence, there is no way to tell that the device is not
a regular PCI device.

there is nothing in the ALSA driver for the HDSP that is conditional
on the h/w being a cardbus device or not, because we don't (and likely
can't) know that it is.

sorry. FWIW, i have an ENE 1411 and it works OK with my hdsp at period
sizes below a certain threshold. i don't know if its the same problem
or not.
