I will probably do that (maybe), but nonetheless I have identified the offending ACPI module. If I blacklist the 'processor' module then b43 works. I strongly suspect that kernel ACPI does not at present deal correctly with Atom N270 idle states. As a side note, with kernel 2.6.32 the 'thermal' module is not dependent (so far as loading is concerned) on the 'processor' module and is not troublesome, although I am not certain it actually does anything (cpu temperatures and operation of the fan seems to be controlled by the BIOS on my machine): nonetheless I install 'thermal' out of superstition. Anyway, that appears to be a temporary fix until any ACPI bugs are sorted out.
