[SLE] sierra wireless aircard 860 problems

Hi, I've been unable to get the Sierra Wireless PCMCIA AirCard 860 (GSM/GPRS data card) working on a desktop running Suse 10.1 (2.6.16.13-4-smp). I've used a PCMCIA to PCI Interface Card Drive. The card is detected, with ttyS1 (assigned IRQ=201) but the UART displays "unknown" and I am unable to use minicom. NOTE: I was able to get the card working on IBM ThinkPad R51 with Suse 10.1. # dmesg ACPI: PCI Interrupt 0000:05:00.0[A] -> GSI 21 (level, low) -> IRQ 201 Yenta: CardBus bridge found at 0000:05:00.0 [0000:0000] Linux agpgart interface v0.101 (c) Dave Jones agpgart: Detected an Intel 915G Chipset. agpgart: Detected 7932K stolen memory.

Also to be noted is the null ISA IRQ mask for the cardbus bridge (Yenta socket) as shown in dmesg output. I've tried updating /etc/pcmcia/config.opts with "exclude irq 201" and the problem persists. I also tried giving boot time kernel options pci=assign-busses acpi=off, but still problem persists.
