In fact, fonts were the underlying problem, and I just got xdm to run :-)

Some evidence that it matchs:
  agp0 at pchb0: detected 7932k stolen memory
  agp0: aperture at 0xb0000000, size 0x10000000
  vga0 at pci0 dev 2 function 0: Intel 82915GM/GMS,82910GML
                                     Integrated Graphics Device (rev. 0x03)

The remaining problem is having a large square as a cursor, which is
probably related to:

    (II) I810(0): Allocated 4 kB for HW cursor at 0xffff000 (0x01936000)
    (WW) I810(0): xf86AllocateGARTMemory: allocation of 4 pages failed
            (Cannot allocate memory)
    (EE) I810(0): Failed to allocate HW (ARGB) cursor space.
