The isapnp probe on boot is really slow. I suspect that isapnp is not
relevant for systems made in the last 5 years, because ISA and EISA went
the way of the dodo. Is isapnp necessary for any modern hardware?

Would disabling isapnp based on the age of the system make sense?
Alternatively, what other ways are there to speed it up?

Thought of a another way: if the machine has SMBIOS, and SMBIOS says that
it doesn't contain any ISA/EISA slots, then don't run the isapnp probe.

That's a very nice idea. pmf on x86 has the ability to set this flag (cf. arch/x86/x86/platform.c), which the isapnp driver could lookup in its match function.
