(Same problem exists in the 4.x releases.)

>Description:

LINT (or NOTES, in -current) mentions the PQ_CACHESIZE setting but doesn't
tell me what the argument refers to.  For example, the default is

options         PQ_CACHESIZE=512        # color for 512k/16k cache

What do 512k/16k refer to?  I have an AMD Athlon chip with 

Data TLB: 24 entries, fully associative
Instruction TLB: 16 entries, fully associative
L1 data cache: 64 kbytes, 64 bytes/line, 1 lines/tag, 2-way associative
L1 instruction cache: 64 kbytes, 64 bytes/line, 1 lines/tag, 2-way associative
L2 internal cache: 256 kbytes, 64 bytes/line, 1 lines/tag, 8-way associative

What do I use for PQ_CACHESIZE?  Do I even use PQ_CACHESIZE?  Is it deprecated?
Help?

>How-To-Repeat:

Read /sys/i386/conf/LINT or /sys/conf/NOTES
>Fix:

You got me there.
