I wonder whether there isn't some dependency on the graphics chip being
used.

I'm running r248589 AMD64 and didn't have to touch a thing to get X
to start.

But I'm using an older, presumably less demanding graphics chip:

vgapci0_at_pci0:1:0:0:     class=0x030000 card=0x19051462 chip=0x0a6510de rev=0xa2 hdr=0x00
    vendor     = 'NVIDIA Corporation'
    device     = 'GT218 [GeForce 210]'
    class      = display
    subclass   = VGA
    bar   [10] = type Memory, range 32, base 0xfb000000, size 16777216, enabled
    bar   [14] = type Prefetchable Memory, range 64, base 0xc0000000, size 268435456, enabled
    bar   [1c] = type Prefetchable Memory, range 64, base 0xde000000, size 33554432, enabled
    bar   [24] = type I/O Port, range 32, base 0xef00, size 128, enabled

Above all, bar [14] is only half as large.
