X11 on XP1000 with ELSA Gloria Synergy

I just installed OpenBSD 3.9 on an XP1000 with an ELSA Gloria Synergy PCI
graphics card.  Now I'm trying to bring up X11 (using the X11 binaries in the
distribution directory).

Toward the end of /var/log/Xorg.0.log:

----------
(**) GLINT(0): Depth 24, (--) framebuffer bpp 32
(==) GLINT(0): RGB weight 888
(==) GLINT(0): Default visual is TrueColor
(==) GLINT(0): Using gamma correction (1.0, 1.0, 1.0)
(==) GLINT(0): Using HW cursor

(--) GLINT(0): Linear framebuffer at 0x81000000
(--) GLINT(0): MMIO registers at 0x80000000
(--) Machine type has 8/16 bit access

Fatal server error:
xf86MapVidMem: could not mmap /dev/mem [s=20000,a=80000000] (Invalid argument)
----------

The kernel does have APERTURE set and I do see

# sysctl -a | grep aper
machdep.allowaperture=1

I've included the dmesg output below, but it looks as though the box does have
BWX support:

cpu0: Architecture extensions: 307<PAT,MVI,CIX,FIX,BWX>

Any suggestions?

Thanks,

Michael
