Perhaps this doesn't help... I do RELENG_7 based images

parameters extracted from in-core disklabel are:

Interesting, that's classic USB-HDD geometry (255H, 63S).
Can you tell me what make, model of stick this is?
It could be that the cylinder change is what's confusing the BIOS. I
will need to do some tweak to make sure the cylinder calculation is
right for the stick's capacity.
The A/Open MX3S has no USB-HDD mode. It appears to have the same delay
issue, however, it didn't see any difference between the USB-HDD
geometry image and the USB-ZIP geometry image.

That device uses USB-ZIP style geometry (64H, 32S), and based on the
"last block", 1953792 / 2048 is 954 cylinders exactly, which is how it
came factory formatted.
So I should probably give it a shot based on this. To get something up
and running I've been using generic methods in the NanoBSD patch, I
haven't sized the MBR geometry specifically to the device.
By my reckoning your stick is just under 512MiB, based on the geometry
you provided:
parameters to be used for BIOS calculations are:
cylinders=62 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
start 32, size 1001440 (488 Meg), flag 80 (active)
beg: cyl 0/ head 1/ sector 1;
end: cyl 488/ head 63/ sector 32
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
