[PATCH] devices.txt bugs

[Geert Uytterhoeven]

This patch fixes two things:

  - Correct the minor numbers for the frame buffer devices.  We have room for
    32 frame buffers since about one year, with more room for future expansion
    to 256.  (promised to go in by HPA on Fri, 24 Mar 2000 01:47:05 -0800).

  - Fix a typo in the minors for the A2232 serial card

How is this supposed to work? /dev/fb1 can either be 29,1 or 29,32. But
not both at the same time.

The idea is that you're supposed to change your /dev nodes; the old /dev
nodes are supported for a bit.  The device list has been updated.
