Panic when ifconfig'ing nge card.

We are rebuilding a system which has a Netgear GA621 (using the nge
driver) installed, and which had run 5.2 & 5.3 pre-releases on amd64
(it's a Dual Opteron box - Tyan Thunder motherboard)

We are now intending to make it a backup server and it is running
5.4-PRE/i386 (cvsupped just under 20 hours ago), and when we try to
configure nge0, after coming up for around 10 seconds it panics.

nge0: <National Semiconductor Gigabit Ethernet> port 0x9800-0x98ff mem
0xfb8ff000-0xfb8fffff irq 29 at device 1.0 on pci1
nge0: Using TBI
nge0:  1000baseSX, 1000baseSX-FDX, auto

% ifconfig fxp0 down
% ifconfig nge0 netmask

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x8

instruction pointer     = 0x8:0xc055bdda

processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 39 (irq29: nge0)
trap number             = 12
panic: page fault
Uptime: 21m3s
Cannot dump. No dump device defined.
Automatic reboot in 15 seconds - press a key on the console to abort

Any ideas? I have already tried turning of HTT (can't), ACPI (same
effect).  We can't run amd64 since we know the 3ware driver isn't 64-bit
clean and locks up the system under heavy I/O load.  We could just live
w/ 100baseTX, but we would rather be running GigE...
