You are looking in the wrong spot .. sort of.  The boot-up sequence
is going to be in the ipl (initial program load) and startup libraries.
It isn't in the kernel itself ... which is just the beneficiary of all
of the hard work that the IPL/startup pieces perform.

Also, this is QNX 6.3.2, not QNX 4.25, so the source is going to be
quite different.  I don't know if you were looking at one as a reference 
to the other, but you won't find that here.

If all you wanted to do was to make a Neutrino OS image that could boot
from USB then run an appropriate configuration tool to format a compact
flash drive to a QNX 4 filesystem and install the QNX 4.25 image (assumed
to be pre-built), then that is not hard at all assuming you have a system
that can boot from USB mass storage devices.

You don't need the source for this, you just need to create a custom image
and slap it on the USB key as a boot image.  In fact you should be able
to even use a FAT32 filesystem with a custom MBR put in by the QNX dinit
or fdisk utility.

Hope this helps,
 Thomas
