Being old-school, I'm very much for both of these statements.  From a 
"customer" 
perspective, about the only thing that's forced me to learn more than I ever 
wanted about 
the inner-workings of the Linux kernel is the absence of peripheral support at 
the kernel 
level.  There are no drivers provided for the DIOs and the ADCs.

The example code works well enough (thanks!), and I don't have very strict 
timing 
requirements, but I would like to get get the status of all the peripherals at 
some 
reasonable frequency (say 100Hz?).  Seems like not too much to ask considering 
we can 
execute 2 million instructions at 100 Hz.  I'm using the on-board ADC, all of 
the DIOs, 
XDIO edge counter, as well as other XDIOs (TS-7260).  Its not exactly possible 
to do all 
this with stock software and its minimum of a 10ms sleep.  Driving the ADC from 
userland 
and debouncing DIOs pretty much throws a wrench into the works.  About 10 Hz is 
the 
best I can manage, which is actually passable for my application (but only 
thanks to the 
XDIO edge counter).

Frankly, I could care less about Eclipse and the rest of that gobbledygook.  
Sleeping on a 
FIFO, developing in BBEdit over FTP, and self-hosted compiling on a chrooted 
USB 
thumbdrive is just fine by me.  "If it ain't broke - don't fix it".
