Right.  I tried RC9 on some OHCI hardware I have locally,
and none of it seems to have this problem.  If I had more
PCI slots, I could test more OHCI silicon ... but those
are going the way of the serial port (at least on PCs).

The only regresion I uncovered is that my OMAP1 OSK stopped
booting sometime after RC2; that's not because of OHCI.

I don't recall anything unusual about ALI and OHCI.  They
worked fine for me in some K6 and K7 hardware I had back
then ... then they got renamed to ULI, bought by NVidia,
and killed.
