-CURRENT panic in kmem_malloc (?)

	I upgraded to -CURRENT:

FreeBSD 5.2-CURRENT #1: Sun Feb  1 15:53:50 EST 2004

	 and have since been getting panics, possibly in kmem_malloc:

Panicstring: kmem_malloc(-791617536): kmem_map too small: 20107264
total allocated

	Kernel config file and stacktrace are appended.

# Parallel-Port Bus
#
# Parallel port bus support is provided by the `ppbus' device.
# Multiple devices may be attached to the parallel port, devices
# are automatically probed and attached when found.
#
# Supported devices:
# vpo	Iomega Zip Drive
#	Requires SCSI disk support ('scbus' and 'da'), best
#	performance is achieved with ports in EPP 1.9 mode.
# nlpt	Parallel Printer, use _instead_ of lpt0
# plip	Parallel network interface
# ppi	General-purpose I/O ("Geek Port")
# pps	Pulse per second Timing Interface
# lpbb	Philips official parallel port I2C bit-banging interface
#
# Supported interfaces:
# ppc	ISA-bus parallel port interfaces.
