Toshiba Satellite 4070CDT. APM has worked without any problems, in
2.4 and earlier kernels, both Red Hat kernels and vanilla ones.

I'm not using X :)

I am using vesafb, as my text console. Same with 2.4.

I've just noticed a notable change: the Toshiba SMM driver. That is
now configured in, whereas before it was a module and I never loaded
it. Although I don't use it, when it initialises it does some funky
SMM stuff - might that be breaking resume?
