	Um, I thought RHEL4 worked with firewire just fine.

	The configure will always default to the latest distro
kernel-devel if you have it installed.  The
--with-kernel=/usr/src/linux-2... option will force any kernel source
path you like.

	Yes, i_sem got renamed.  There are many parts of the kernel that
have changed.  When SLES10/RHEL5 start coming out, you'll see oracleasm
fix that up.  As oracleasm is an enterprise-system only thing, I don't
have the time to keep it mainline happy.  Sorry :-(

	Again, I could swear RHEL4 firewire was supposed to work.
Otherwise, you're probably going to have problems.  You could try
patching oracleasm up to date, I guess.  the struct backing_dev bits
have changed, i_sem->i_mutex and the associated mutex_lock() calls, etc.
