Custom Kernel for FreeBSD Installation

How do I go about replacing the kernel on the FreeBSD installation CDs?
I assume it's as simple as replacing the relevant files in the ISO
image, and that if I look at "make release", I can figure out how the CD
image gets generated.
I'm trying to install FreeBSD onto a HP ProLiant DL380 G3 with a Smart
Array 5i controller, for use as a file server. Rather than use Smart
Array's RAID features, I want to use ZFS's RAID-Z1/Z2, so I have
configured 18 RAID-0 volumes, each consisting of a single drive attached
to the Smart Array controller. This totals 18 drives, so at boot time,
the ciss(4) driver logs the following error:
ciss0: <Compaq Smart Array 5i> port 0x3000-0x30ff mem
0xf05c0000-0xf05fffff,0xf04f0000-0xf04f3fff irq 10 at device 3.0 on pci1
ciss0: PERFORMANT Transport
ciss0: adapter claims to report absurd number of logical drives
(18 > 15)
device_attach: ciss0 attach returned 6
According to Paul Saab
(http://lserinol.blogspot.com/2012/03/freebsd-ciss-driver-logical-drive-
limit.html), the constant CISS_MAX_LOGICAL limits the amount of memory
used by the driver for DMA by default.
Best wishes,
