CONFIG_KEYBOARD_ATKBD and CONFIG_KEYBOARD_HIL
have nothing to do with each other. Reading your reply below,
it seems, that you will only need CONFIG_KEYBOARD_ATKBD.
I think, the HUB is only used to "transport" the PS/2 signals to your computer,
and uses some cables inside the HIL cable.

Yup, then it's definitively a PS/2 keyboard.

Yes. My HUB has only HIL connectors and is for a 715/64.

Ok.

I would be interested in your dmesg log.
Mine (HIL only!) looks like this:

mice: PS/2 mouse device common for all mice
serio: GSC PS2 keyboard port at 0xf0108000 irq 69 @ parisc2:0:11
gscps2.c: timeout - could not write byte 0xed
gscps2.c: sending byte 0xed failed.

-> OK, since I only have a HIL keyboard.

serio: GSC PS2 mouse port at 0xf0108100 irq 69 @ parisc2:0:12
gscps2.c: timeout - could not write byte 0xed
gscps2.c: sending byte 0xed failed.

-> OK, since I only have a HIL mouse.

HP SDC: HP SDC reports successful PUP.
HP SDC: HP SDC at 0xf0201000, IRQ 126 (NMI IRQ 125)
HP SDC: New style SDC
HP SDC: Revision: 1820-4784
HP SDC: TI SN76494 beeper present
HP SDC: OKI MSM-58321 BBRTC present
HP SDC: Spunking the self test register to force PUP on next firmware reset.
HP SDC MLC: Registering the System Domain Controller's HIL MLC.

-> OK, the HIL stuff is detected. (BTW, test this after power-cycling the machine!)

and then nearly at the end of dmesg:
HIL KEYB: HIL keyboard found (did = 0xcf, lang = german)
input: HIL keyboard, ID: 207
HIL PTR: HIL pointer device found (did: 0x68, axis: relative)
HIL PTR: HIL pointer has 3 buttons and 1 sets of 2 axes
input: HIL pointer device (HIL mouse), ID: 104

This is now HIL keyboard and HIL mouse.
So my HIL mouse is detected, but doesn't seem to work yet.... :-(

No. You should disable HIL_KBD (but it doesn't hurt either).

As said above: Hard Power-cycle the machine before each test!
Furthermore you might try to increase the value of mdelay(6); in line 168
in file linux-2.6/drivers/input/serio/gscps2.c...
Maybe it's a timing issue ?

This is what you should have in your .config:
CONFIG_SERIO_GSCPS2=y
CONFIG_INPUT_KEYBOARD=y
CONFIG_KEYBOARD_ATKBD=y
CONFIG_INPUT_MOUSE=y
CONFIG_MOUSE_PS2=y
