This wasn't tested against 2.6.30-rc1 was it?

See the recent fixup patch I sent.  There's a spi_master->modebits
mask that should have been initialized, and which eliminates the
need for tests like that ...

... also the SPI core now provides a *standard* format debug
message for that stuff.  It also handles one more thing, which
I expect to see fixed in a v8 of this patch ... :)
