Notepad works. This is not a windows partition; it is a volume I defined in winecfg as D:. I tried running some things from explorer.exe; most of the games that run under wine in the 32-bit version of the OS will not run, producing lots of error output similar to what I already posted. Examples: Doom3, Wordstar. Some things do run, including some games that expect DirectX, so I don't think it's that problem. Is there a problem running 32-bit windows apps in 64-bit wine?
