True. This is exactly where our kernel modules have a weakness. Or
differently put, where our kernel configuration has its weakness.
A module is pretty much all-inclusive. A kernel configuration is
minimalistic by nature (hence, one would actually expect reduced
functonality). Mixing them gives unwanted results in a pre-dominantly
modular configuration. One way to attack it is to make a kernel
configuration the same as a bundled set or a preloaded set of
modules. This means for example that if you configure ppc(4) into
the kernel, you get the acpi attachment even if you don't have device
acpi configured into the kernel. This of course may result in
unresolved symbols, so it's not a trivial solution. If it's a
solution at all...
