I could for the time being, but this hasn't worked for me in the past. Usually
what happens is the PC breaks down, and the customer swaps in a new
backplane+SBC and moves all their PCI cards over. I then find I need to update
the kernel just to get the Intel DRM to work properly on the new CPU. Some of
these systems were installed back in the Linux 2.6 era, so I've gone through
several "Intel DRM not working" steps ever since CPUs started getting
integrated graphics. 2028 will come fast.

One thing worth mentioning though--these 3com cards are all PCI. They still
work perfectly fine on the newest hardware. Your subject says you're dropping
old ISA and PCMCIA support, so I don't fully understand why you included 3c59x
in the mix. Phoronix picked up this patch
(https://www.phoronix.com/news/Linux-Old-Network-AI), and according to the
comments, there are still people who use these cards (3c905s were very popular
back in the day). Would you be willing to leave this driver in mainline?

I'm sorry, but I already have enough going on to take up another maintainer
role. However, I thought Greg had some rule in place that said the stable
branches don't get any patches applied unless they also hit mainline. Is there
some exception for drivers in stable that don't exist in mainline anymore?
