Actually Philips has a nasty habit of advertising things as "OHCI-compatible"
(and ISTR "EHCI-compatible" too) where the compatability is limited to a
subset of the registers ... but where the in-memory data structures are so
incompatible that a real OHCI (etc) driver can't be modified to use them.

That's why we have an isp116x-hcd driver, instead of hacks to the OHCI code
to understand the "Philips Transfer Descriptors" (PTDs) as well as the real
OHCI-conformant TDs.

So ... do use 2.6.current, but don't modify either OHCI or EHCI drivers
unless Philips has really Seen The Light and decided to actually conform
to those specs.
