Well, I followed the advice of all the helpful people in this thread and have it up and running, defaulting to VESA, and my wifi connected without a hitch. So, thanks to all of you for your speedy and helpful responses!
Now that I’m getting a chance to explore the OS and the apps a little more fully, I’m enjoying it so far. Still a few kinks to work out, chiefly right now being that WebPositive doesn’t seem to like a lot of my usual sites. I tend to get a “URL cannot be shown” error on even the most basic sites about 9/10 times. Even google.com and wikipedia return this message.
Since PulkoMandy suggested using listdev to get a better look at my hardware, which will hopefully aid in my display driver issue, here’s the info dump I get:

The display driver shown in Screen when I first booted without changing the default to VESA was “Intell GMA (i965GM)”. Under that driver, I had a bad stretching effect that gave my cursor a doubled appearance with a cursor on each end of a white line about half an inch wide, and text blocks would be cut into pieces with long gaps. It seemed to apply to the whole screen, as the Haiku logo on the background only showed “HAI” and the launcher was entirely offscreen. Apologies for not having a screenshot of what I was seeing under that driver.
