new 6.1 install will not boot

I got it more or less working, although not completely set up, and
then that 10GB disk died:  click -- kerthunk -- click -- kerthunk
continuously, even after cycling power, even with only the power
connected :(

After replacing it with a 160GB Hitachi, and reinstalling Windoze,
Linux, and FreeBSD (in that order, as before), I seem to be back at
square one -- FreeBSD won't boot -- but the details are different.
Partition Commander now has:

  Ptn    size   ----- type -----  1st sector  # of sectors
  P0     250M   FAT32      0x0B          63        514017
  P1       7M   Linux ext2 0x83      514080         16065
  P2   41.99G   Unix       0xA5      530145      88068330
  P3   85.75G   Extended   0x0F    88598475     179831610
   L0   43.75G   FAT32      0x0B    88598538      91763217
   L1     400M   Linux swap 0x82   180361818        819252
   L2   41.60G   Linux ext2 0x83   181181133      87248952

Sysinstall had not commented about the geometry with the 10GB disk,
but it did this time; and as suggested I let it do what it wanted.
The Dell BIOS will not tell me what it thinks the geometry is -- it
just says the drive is EIDE -- so I have no direct way of verifying
sysinstall's geometry; however the first BIOS partition is a
working FAT32 and per the instructions that "should" be enough for
sysinstall to have gotten it right.  (The second BIOS partition is
a Linux /boot, which also works.)

The install appeared to succeed, and the FreeBSD boot manager does
successfully boot Windoze and Linux, but all attempts to boot FreeBSD
from the hard disk fail.

The following was transcribed by hand, so there might be some typos;
and I've added some notes to the right of the lsdev output.  I've
also confirmed, using the loader's "ls", that there is no visible
file named 'kernel' in the root directory, nor anywhere under /boot,
/rescue, or /sbin.  Where is it supposed to come from, and how do
I get it where it needs to be without reinstalling the whole thing
*yet again*?
