uboot & bootable USB on t5325


I'm totally new to the arm arch, so I'm sorry if any of this post
doesn't make sense ;)

I have a couple of new HP t5325 thin clients for testing. I don't have
ready access to a serial console, so I'm hoping that I can find some
other way in. Ultimately I would like to have these netbooting ltsp
via tftp or some other means. Failing that, a debian install to the
embedded flash would also be handy.

Using HP's included ThinState utility I have created a bootable USB
stick that uses a script to write a gzipped image to the embedded
flash using dd. I'm wondering about the prospect of replacing that
image with something debian-like, preferably something that could be
configured to pull my ltsp image over the network.

Failing that, the bootable USB stick also has a
/uboot/u-boot-3.4.19_V12_1016.bin file that I'm thinking could perhaps
be replace with something a little more useful to my purposes.

Does any of this sound reasonable? Feasible?

Here's some specifics on the hardware.
