You may lack features like acceleration etc. But you gain stability.

That's an upstream issue.

We made several attempts at fixing it. Introducing chipset detection
late in the release cycle could have lead to more issues.

From the output of the bug script (included in your report), lspci returned:
| 00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03)

I think the FAQ tells you exactly how to do it? IIRC, vesa only does
4/3 resolutions. fbdev uses the framebuffer. I'd say fbdev (spares you
a reboot to disable KMS), and vesa if it doesn't work well.
