[syslinux] SYSLINUX 3.70-pre19 and the frozen USB keyboards

[H. Peter Anvin]

I have pushed out SYSLINUX 3.70-pre19.  This includes a workaround that 
I have some early indications might actually resolve the "frozen USB 
keyboard" problem.

If you have a system with this issue, I would *greatly* appreciate:

a) if you could test it;
b) if it works, if you could verify that 3.70-pre18 *DOESN'T* work.

This would be incredibly useful!

Thanks,
