First, I would say update Wine. 1.1.8 is pretty old and I believe that particular version had a regression in it that caused "Invalid address" errors.
Also, you should use the standalone installer for Chrome. The installer that downloads Chrome doesn't work. You can get the standalone installer here:
http://www.google.com/chrome/eula.html?standalone=1. You can save the exe anywhere.
Run:
$ winecfg
and set your Windows version to Windows XP.
Then run:
$ wine /path/to/ChromeSetup_172_28.exe
(ChromeSetup_172_28.exe is the current version...it may change)
Same goes for Firefox. They both work pretty well for me on FreeBSD 7.2 with Wine 1.1.23 (Wine 1.1.25 is out, but I haven't had a chance to update).
