my take on this is:

	- we should convert all autoconf messages to the relevant
	  aprint(9).  this is its own project.

	- we should convert all other device logging (whether printf
	  or log based) to use a device_*() function that does what
	  we want.)  this is another project.

	- non-device log/printf should be ignored for these projects.

this means introducing a device_log(), probably like this:

void device_log(device_t dev, int level, const char *format, ...);

thanks!  this clean up is sorely needed.
