actually, it was fixed in -current long time ago,

Revision 1.128 / (download) - annotate - [select for diffs], Wed Dec 14 
22:27:48 2005 UTC (9 months, 1 week ago) by mux
Branch: MAIN
Changes since 1.127: +2 -2 lines
Diff to previous 1.127 (colored)

Fix a bunch of SYSCTL_INT() that should have been SYSCTL_ULONG() to
match the type of the variable they are exporting.

Spotted by:	Thomas Hurst <tom at hur.st>
MFC after:	3 days

i guess mfc did not happen in 3 days.

thanks,
