The settings in the LINT file are not necessarily the defaults, rather 
mere examples.  The default value for PMAP_SHPGPERPROC is 200 (defined 
in the source file /usr/src/sys/i386/i386/pmap.c).  I would recommend to 
increase it by 100 until the messages stop.  We use 300 on our servers, 
for instance.

Regards,

    Uwe
