Holtek HT80232 NIC unrecognized on FreeBSD 5.4-RELEASE

[jackqq]

My ethernet adapter's chip is Holtek's HT80232. It seems to be not
recognized by the GENERIC kernel or any if_*.ko module.

I looked for its driver for FreeBSD. Googling "holtek" "ht80232"
"freebsd", I was shown some clues that FreeBSD seemed to support this
chip. The clue was found in /usr/src/share/misc/pci_vendors, where it
said

12C3    Holtek Microelectronics Inc.
        0058    HT80232 LAN Adapter (NE2000-compatible)
        5598    HT80229 Ethernet Adapter (NE2000-compatible)

Later, I found that the driver ed(4) supported NE2000 NICs, and, it
was included in the GENERIC kernel. But when the machine booting with
GENERIC, the card was not attatched with that driver or even any other
driver. My dmesg(1) is excerpted below:

        intpin=a, irq=18

pci2: <network, ethernet> at device 4.0 (no driver attached)

I noticed that the card was found on pcib2 slot 4, because the vendor
and device codes matched the ones in the FreeBSD source code. Then, I
discovered ed.0 was disabled in /boot/driver.hints, so I modified that
file like this:

# hint.ed.0.at="isa"
# hint.ed.0.disabled="1"
# hint.ed.0.port="0x280"
# hint.ed.0.irq="10"
# hint.ed.0.maddr="0xd8000"
hint.ed.0.at="pci"

However, this didn't work either.

Could somebody give me some suggestions on what I should read or where
I should check next? Thanks in advance!
