The aperture driver you're looking for is in our -current xsrc tree.

/usr/xsrc/xc/programs/Xserver/hw/xfree86/etc/apNetBSD.shar

I built it from there and it seems to work fine.  But what exactly
*is* "MTRR support"?  I'm not noticing any significant improvement in
performance or anything else, while running X with this driver.

relevant dmesg output:

pci0 at mainbus0 bus 0: configuration mode 1
pci0: i/o space, memory space enabled
ppb0 at pci0 dev 1 function 0: VIA Technologies VT82C598 (Apollo MVP3) PCI-AGP (rev. 0x00)
pci1 at ppb0 bus 1

vga0 at pci1 dev 0 function 0: 3Dfx Interactive Voodoo3 (rev. 0x01)
XFree86 aperture driver version 1.99b
Pentium Pro MTRR support enabled
