APC Back-UPS CS 350VA USB and SuSE 7.3

Greetings! I'm thinking about getting an APC Back-UPS CS 350VA USB to automatically shutdown my small file/DSL/firewall server (AOpen micro-ATX motherboard, Cyrix M2-333Mhz, 128MB, 10GB IDE hard drive, SCSI cdrom drive, and no monitor). Does anyone have any experience with this particular UPS? Does the stock SuSE 7.3 kernel support a USB UPS or do I have to hack and patch the kernel to make it work? Recommend a similar model with serial support for under $100 USD? Thanks! Christopher Reimer
