I installled SuSE 8.2 on my Compaq 2170 with no problems. I needed to dual boot with WinXP, so I used Partition Magic to resize the NTFS partition, and leave most of the hard drive for linux. All of the hardware was recognized and configured automatically (except for the winmodem, of course). ACPI required turning on the acpid daemon in YAST. Getting my NetGear MA401RA wireless card working took some doing, but now works.
