	I just did that -- to create a swap file :)

	No, there's another one regarding a free page, still in
	the vm_* area.

	So far I was able to compile bash (and apache, for kicks) --
	seems to me that the ATA disks are running in PIO mode, even though
	I can't explicitly see it (atacontrol doesn't say anything special),
	I see 85-95% interrupts when untarring something with many files.

	I tried to build world on my x86 machine last night (5.2-BETA),
	and IT panic'ed in the middle of compiling some PPC code :-(
