Looks like you've found the right answer there.  Unfortunately you've 
hit Catch22: in order to fix the boot problem, you need to patch the 
kernel.  In order to patch the kernel, you need a running system.  In 
order to get a running system you need to fix the boot problem...

Probably your best bet is to pull the disk out of your i7520 box and 
attach it to some other machine where you can install FreeBSD on it.  At 
the same time try applying the patch from PR i386/74829 and building a 
kernel with it applied.  If you can extract the patch either from the PR 
(http://www.freebsd.org/cgi/query-pr.cgi?pr=74829) or the e-mail you 
quoted, then to apply it:

     # cd /usr/src
     # patch -p 2 < patch.txt

Note that extracting the patch may be harder than you expect, as mailing 
systems and cut'n'paste tend to wrap lines or convert tabs to spaces and 
other such damage.

Then rebuild the GENERIC kernel and install it onto your new drive. 
Instruction for building a kernel are here:


http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html

Don't let your Gentoo experience tempt you into trying to chroot 
yourself onto the new drive -- while that could certainly be made to 
work, it's not something that gets done very often so you'ld end up 
having to debug things as you went along.  Just use sysinstall(8) to 
install on the appropriate disk while it's attached to a spare system, 
and then boot up your spare system from that drive to do the kernel builds.

	Cheers,
