This patch requires
commit 33a2d9226557c298a5df13b95bd31b8b1d749918

pata_pcmcia: Add support for dumb 8bit IDE emulations
found in #for-testing. Should that patch be promoted to #upstream
(queued for 2.6.25), and then this patch applied on top, also in #upstream?
If you're curious, here is the current content of #for-testing
(attached). You need to poke me to move stuff from #for-testing to
#upstream, since I dropped it into #for-testing at your direction.
(for other readers, #for-testing is a branch always merged into #ALL and
thus -mm)

libata: fix (hopefully) all the remaining problems with devices failing
setup/identify
pata_pcmcia: Add support for dumb 8bit IDE emulations
libata-core: Don't have screaming fits over DF/ERR combinations
libata/pata_it821x: Improve handling of poorly compatible emulations
