Noted. The GFP_DMA flag just confused for a few minutes, but looking at
some DMA Documentation, apparently all kmalloc() memory is safe. Good
to know. :)

Actually, no. According to datasheet page 97, channel 0 has
bit 2 of the register, which is SR_SUB_MODE, set to 0, while for the
others it'll be one. There's also a 100% bitrate increase when you go
from channel 0 to channels 1 through 10. The page influences the next
higher bit in the register, bit 3, which is the BPSK_QPSK switch.
