Chris/Lee,

In kernel-2.4, the multiport 'latch' is required. Most major distros default 
kernels are compiled with multiport support, and so the set_multiport line 
would execute properly (at least when there's no ioport interrupts) and a 
kernel recompile would not be required.

This has completely changed in kernel-2.6 ... they've reworked the multiport 
serial support quite a bit.

We've been working with Mainpine to help them develop a recommended 
configuration procedure for kernel-2.6, and we each have 2.6-based fedora's 
in our labs in testing. So far, it seems like you can run all the setserial 
commands _except_ for the multiport latch (which is not relevant to 
kernel-2.6 and as far as we can tell will never work) and it should 'just 
work'.

Look for an update on Mainpine's website once they've finalized their 
official recommendations.

-Darren
