At this stage I've run out of time to test the M-Audio Rev in the
XP1000 and see if the MMAP disable patch help there.
Given that it fixes es18xx and cmipci on the PWS600au and that those
worked without trouble on the XP1000, you'd _expect_ not, but the OOPs
you posted before seemed to indicate that it stands a fair chance afer all.
Oh, by the way, note that it only disabled mmap for CONFIG_ALPHA_MIATA due
to your report of es18xx working fine on the XP1000, so you'll have to
change that to CONFIG_ALPHA_DP264 for the XP1000 to actually test it there:
(or just delete SNDRV_PCM_INFO_MMAP from the info structures in the driver
as Takashi earlier instructed)
