Fatal trap on booting from floppies

[David Calinski]

Hello FreeBSD hackers,

I hope this is the right place to ask this question:
how to create own set of bootdisks (floppies)?
Any hints, links? Yes, I was googling for it, without good results. :-/

Why I need to create them:
I have a problem installing FreeBSD on an old notebook (HP Omnibook 5700CT, 
it's a Pentium166mmx)

This hardware doesn't have a cd-rom, so I use bootdisks (floppies).
But when second standard disk (mfsroot.flp) finishes booting, I got: (this is 
from FreeBSD-5.1 bootdisk)

(...)
inab0: <PCI-ISA bridge> at device 1.0 on pci0
isa0: <ISA bus> on isab0
pci0: <display, VGA> at device 2.0 (no driver attached)
cbb0: <TI1131 PCI-Cardbus Bridge> at device 3.0 on pci0
cardbus0: <Cardbus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0

The same happens also with bootdisk-floppies from: FreeBSD-5.0, 4.8, 4.9RC2, 
and bunch of older versions as well. :-(
Now, I would like to track it down somehow - compile with more debug things,
compile most recent FreeBSD version (maybe problem was fixed), but I simply 
don't know how - how to create own floppy-bootdisk?
(I do have more machines running FreeBSD, so I can create them there).
Or maybe you have other ideas: how to avoid FreeBSD to try using pccard 
driver ? (maybe pccard driver is a problem here).

I obviously have tried standard things: turning off power management in bios, 
tried different physical floppies, so they are not the problem here...

Ah, maybe it's because of SVGA controller/driver
(Chips & Technologies 65554 SVGA controller).
Anyways, someone with a diffrent Omnibook had the same problem:
http://www.freebsd.org/cgi/query-pr.cgi?pr=39229

And this hardware does work with most recent OpenBSD, but I really would like 
to use FreeBSD on it... *sigh*

So what can I do? :-(
Thank you in advance.
