Enabling DMA.

| The weird part is this: The right IDE module for my hardware is loaded
| (in this case via82cxxx).  There is nothing suspicious in lspci (it
| sees and correctly identifies the IDE controller).  The only notable
| bit of dmesg's output is this:
| 
| Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
| ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
| 
| Any ideas what to do about this?  It seems like the via82cxxx module
| isn't loaded when the kernel initially encounters the IDE devices, so
| they use some default driver that won't allow me to enable DMA, but I
| have no idea what to do about it except perhaps recompiling my kernel
| myself with the proper bits compiled in instead of as modules.

It seems like there's some fishyness around the load order for
modules, try listing via82cxxx in /etc/modules to make sure it's
loaded before ide-generic.
