The NeoMagic audio device uses the buffer resident in the device
itself, not main memory. That message is telling you that the driver
was unable to map that hardware buffer into the kernel's address
space. It possibly means that you have the device unconfigured in
your BIOS settings (the most likely cause of this message is that the
PCI bus address register for that buffer has not been programmed by
the BIOS at power-up).
