I can understand the desire to enable filtering on a 
subsystem-by-subsystem basis, but I think rather than doing a 
subsystem-specific hack we should do something that any subsystem can use.

Perhaps we could extend the current <level> hack to include a subsystem, 
something like:

<7><x86>Your blort driver seems to be befudged, trying blarfing.

... and something like "loglevel=x86:7,acpi:3,..."
