I am looking for the best way to debug kernel modules/drivers.

I am trying to get a PCI Audio Card (Creative SBLive) working just to do some
testing.  (ie don't want to spend a lot of time on PCI or this particular

In addition we would like to have a way to read registers and other values from
the hardware as we go forward.

What is the best solution?

Are there any good docs on-line for xmon, kgdb, and/or kdb?

I have also read about BDM4GDB and BDI2000.  Is BDI2000 worth the cost?  Are
there other BDM's for the 405 which work well with Linux?

Thanks again,
