Um, actually, I've been running 2.4 kernels on several
laptops over the last year, with no problems other than
devices that aren't supported yet (winmodems, specifically).
In general, everything else worked fine -- including APM,
USB, and PCMCIA. Some folks claim to be using IrDA with
no problems on these same machines but it's not something
I've tried.
The laptops I've used are all HP ones (I *do* work for HP,
after all :-). The following are all running 2.4.10 kernels,
with PCMCIA, using Debian testing:
-- HP Omnibook 500
-- HP Omnibook 6000
I've also got an HP Omnibook 4150 running the latest Red Hat
(I think it's 2.4.6, maybe 7).
Sorry if this sounds like an advertisement; it's not meant
to. Just wanted to clarify that 2.4 Linux on Laptops is
*not* an oxymoron....
