same experience here, asterisk has no problems building but zaptel is 
unhappy.

1. very small problem: 2.6 has the option to use vector based irq 
indexing, so /usr/src/linux/include/asm/irq.h does something a little 
tricky:

#include "irq_vectors.h"

where it automagically selects the appropriate irq_vectors.h for the 
current architecture. there are only a few of these:

/usr/src/linux/include/asm-um/irq_vectors.h
/usr/src/linux/include/asm-i386/mach-default/irq_vectors.h
/usr/src/linux/include/asm-i386/mach-visws/irq_vectors.h
/usr/src/linux/include/asm-i386/mach-pc9800/irq_vectors.h
/usr/src/linux/include/asm-i386/mach-voyager/irq_vectors.h

so it's easy (ahem, kludgy) enough to copy the proper one to:
/usr/src/linux/include/asm/irq_vectors.h
perhaps someone more educated can suggest a proper/elegant solution.


2. very large problem: devfs (which is already deprecated, ha ha) has 
many changes from 2.4 to 2.6.

one of the main issues is that 
/usr/src/linux/include/linux/devfs_fs_kernel.h defined devfs_handle_t in 
2.4 but does not anymore. (although that struct and some other missing 
info can still be seen in /usr/src/linux/fs/devfs/base.c)

also, some references like DEVFS_FL_AUTO_OWNER, DEVFS_FL_DEFAULT, 
devfs_register_chrdev and devfs_unregister_chrdev don't seem to exist at 
all anymore. to be honest, I find devfs very spooky; udev is supposed to 
be better, but I haven't played with it very much.


towards the end of last year, I saw some discussion on LKML regarding 
getting the non-userland bits (i.e. zaptel modules) put into the kernel 
proper. which seems to be the right way to go, but I've not seen any 
mention of it since then. any official or unofficial comments would be 
most welcome...

ps -- other than a few small slips and spills, I've gotten off to a very 
happy start with my shiny new devkit since yesterday morning.
