In fact, it made it worse :(. You didn't specify whether to use the patched version or the unpatched version, so I used the patched version. If you want me to try the unpatched version with vr_tick() commented out, I can do that as well. Interestingly, I did not have to manually set the media with ifconfig; autodetect seemed to work fine (I tested it both with autodetection and after setting it manually: both had the same problems we've been seeing). >Anyway, if you can try that, I would appreciate it.
