Hmm, the file you really should consult here is /usr/src/UPDATING. You
got the sequence slightly wrong (the handbook doesn't always get
updated immediately, UPDATING does). From /usr/src/UPDATING:
To update from 4.0-RELEASE or later to the most current
4.x-STABLE
----------
make buildworld
make buildkernel KERNEL=YOUR_KERNEL_HERE
make installkernel KERNEL=YOUR_KERNEL_HERE
reboot (in single user) [1]
make installworld
mergemaster
reboot

Good, at least you can boot the system....

Looking at the boot messages it is finding ata0 and ata1, the IDE
controllers, but it isn't even probing for the disks. In the config
file for your custom kernel you have commented out important IDE
devices:
# ATA and ATAPI devices
device ata0 at isa? port IO_WD1 irq 14
device ata1 at isa? port IO_WD2 irq 15
#device ata
#device atadisk # ATA disk drives
#device atapicd # ATAPI CDROM drives
#device atapifd # ATAPI floppy drives
#device atapist # ATAPI tape drives
#options ATA_STATIC_ID #Static device numbering
#options ATA_ENABLE_ATAPI_DMA #Enable DMA on ATAPI devices
uncomment ata, atadisk, atapicd (if you have a CD-ROM), and atapifd
and re-build your custom kernel. If that fails, build a GENERIC kernel
and see if that boots.
WARNING: Make a copy of your working kernel (e.g. /kernel.ok). I
suspect it is currently called kernel.old, if so it will get
overwritten (with the broken /kernel) when the next kernel you build
is installed.

You're welcome.
