I can confirm that this is working properly now!
I would also like to say that my USB keyboard performs significantly
better now in GRUB under SeaBIOS on my ASRock E350M1 than it does with
the stock Intel BIOS on my main workstation (Core 2 Quad, Intel board)
Very impressive - Thanks!

I decided to try and debug this myself. The
attached patch is what I
came up with. Within the limitations of typing abilities, it is now
perfect. No sluggishness and no dropped keys. The head == next check
was failing when it should have passed. The reason is that the
toggleCarry bit is often set in endpoint descriptor dword #2, at least
on AMD hardware.
Thanks. I slightly modified the patch and committed it.
Hopefully this change is compatible with qemu,
and other OHCI controllers.
I don't think there are any Intel OHCI controllers. I tested it on
qemu and it looks fine. If you're curious, testing on qemu looks
qemu -L biosdir -chardev stdio,id=seabios -device
isa-debugcon,iobase=0x402,chardev=seabios -fda odin1440.img -device
pci-ohci -device usb-kbd
