Nothing interesting — mostly I get howtos on installing some (proprietary?) 
driver called "wizardpen", and usually with xorg.conf instead of HAL rules.

I've tried enabling "MULTI_INPUT" quirk, as you've suggested:

[root@shinestar:~]$ modprobe -r usbhid
[root@shinestar:~]$ modprobe usbhid "quirks=0x5543:0x0004:0x0040"

It "splitted" the tablet to three devices, as in your case:

I: Bus=0003 Vendor=5543 Product=0004 Version=0100
N: Name="UC-LOGIC Tablet WP5540U"
P: Phys=usb-0000:03:00.0-2/input0
S: 
Sysfs=/devices/pci0000:00/0000:00:06.0/0000:03:00.0/usb1/1-2/1-2:1.0/input/input15
U: Uniq=
H: Handlers=mouse2 event6
B: EV=1b
B: KEY=c01 1 0 0 0 0
B: ABS=1000003
B: MSC=10

I: Bus=0003 Vendor=5543 Product=0004 Version=0100
N: Name="UC-LOGIC Tablet WP5540U"
P: Phys=usb-0000:03:00.0-2/input0
S: 
Sysfs=/devices/pci0000:00/0000:00:06.0/0000:03:00.0/usb1/1-2/1-2:1.0/input/input17

H: Handlers=mouse4 event8
B: EV=1b

B: ABS=1000003

But xinput only gets two of them. They don't send events (xinput test shows 
this). But, looking at Xorg.0.log now, I see that the first device is hooked 
by synaptics driver which cannot init because hardware is unsupported. I know 
why, I've seen overriding rules in hal config. I'll try to reconfigure it to 
use evdev driver.

No, after unbinding I've got the descriptor fully decoded. But I'm afraid it 
doesn't help me...

I didn't get mine to work yet, but the learning experience is here, too :)
