Notebook Problem: refuses to work with 4.x

[RichardKästner]

I am running FreeBSD 5.0 (far out of date, I know) on a Toshiba Satelite 1100.

Basically, I am not willing (nor experienced enough !) to run a system at 
state-of-the-art level. 
So I would really like to go with 4.9 (or 4.10)
However: my "Satellite" can't even boot any 4.xx CD / Floppy.

Boot Process stops with a message complaining about PC-Cards and Controller.
(Sorry, no screen-shots available)

Running 5.0 works so far (with exception of regular compplains about ACPI) - 
but it works! 
Only thing that matters: ports and packages are also out of date.

Since I am using my Notebook on a regular base, I fear upgrades and 
"experiments".

Has anybody a tip for me (besides "buy a new one ..." ;=)


Any hints and help is most appreciated!
