IBM Thinkpad R31 - use 4.10 or 5.3?

[Dave Horsfall]

This was going to be a long story, involving why I'm having trouble 
getting both USB-serial cables and PC-cards to work on this thing, but 
eventually after Googling around and sorting out the wheat from the chaff 
it boils down to this:

IBM R31 Thinkpad 2656KAM.

PC-card slot doesn't work, yet seems to generate spurious interrupts 
whenever an Ethernet packet is received, saying card inserted then 
suddenly not there (yes, it *does* coincide with network activity).

Said slot seems to be a "Cardbus" thing (whatever that is, as I don't do 
Windoze), which I gather is supported in 5.3 but not 4.10?

Delving into the BIOS (ugh), it says that PCI1 and PCI2 are on IRQ10, and 
PCI[34] are on IRQ11 (note that knowledge of Intel's excuse for an 
architecture is not my strong point).

The output of GENERIC's "dmesg" follows.

So, the question is: should I be running 4.10 (because I track whatever my 
boss uses, and my home server uses it for that reason), or should I take 
the plunge and max-out my ADSL line in downloading 5.3?
