I was able to successfully install Icewind Dale II in a Win98 bottle on the following machine:
Soyo SY-7ISA+ Intel i815 Motherboard
Intel Pentium III 866 MHz Processor
512 MB SDRAM
PNY Verto GeForce FX 5200 AGP 8x 256 MB DDR
Creative Labs Sound Blaster Live! 5.1 PCI Sound Card (SB0220)
Samsung CD-RW/DVD Drive Model: TS-H492A/RSWN
Dual Boot openSUSE Linux 10.3/Windows XP Pro SP3
CodeWeavers CrossOver Games for Linux Version 7.1.2
The game executes properly. I have not seen any graphical anomalies. Sound and music also seem to be correct. Cutscenes play properly.
I have not tested multiplayer/network play.
