Thank you for this tip, Hendrik. I get: 

theo@tbox:~$ cat /proc/partitions
major minor  #blocks  name

   8     0    1048575 sda    (this cannot be correct)
   3     0    6297480 hda
   3     1     305203 hda1
   3     2    5992245 hda2

Only *10 minutes later* did sda1 show up:

major minor  #blocks  name

   8     0      31360 sda
   8     1      31280 sda1
   3     0    6297480 hda

Thanks, David.

Could the uhci problems below be part of my problems?

Sep 18 09:50:58 tbox pci.agent[543]:      eepro100: already loaded

Sep 18 09:51:03 tbox usb.agent[632]:      usbcore: already loaded

The rest of the output is similar to the dmesg output at the beginning of this 
mail.

Thanks also for the messages indicating that with the newest kernel my 
problems will be over. I live in hope! (I'm still using 2.4.20-xfs because 
I'm wary of replacing the kernel, having had problems with this in the past.)
