Summary: 2.5.69-mm3 don't compile if:
* crypto HMAC support is off
* PCI IDE chipset is selected but Generic PCI bus-master DMA is off

I tried to compile a kernel for a rescue disk - which is supposed to be small. So I disabled lots of stuff. But crypto and HMAC is necessary, or I get missing symbols. Other crypto algorithms can be turned off.

Why IDE without DMA? Because that particular machine happens to have the broken VIA chipset that IDE maintainers don't want to hear any complaints about. Why compile in DMA support that can't be used anyway? But my PIO only kernel had missing symbols. This is easily worked around by selecting DMA and leaving "PCI DMA by default" off.
