OK, fixed that. Apparently "rtc.ko" conflicts with "genrtc.ko".
Reasonable, they're both drivers for the same hardware. ("make menuconfig"
should have said something...). I don't know why it decided to stop working
now. The only thing I did differently was tell lilo to boot my kernel by
default.
Anyhow, genrtc is 12k, rtc is 18k, so I'm _assuming_ that rtc is bigger
because it has more specific code. So I moved genrtc elsewhere, ran depmod
and rebooted.

Fixed that too. There's a file /etc/network/interfaces, change the line
"auto lo" to "auto lo eth0".

And for completeness:
root@pc:~# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1128 MB in 2.00 seconds = 562.84 MB/sec
Timing buffered disk reads: 62 MB in 3.05 seconds = 20.34 MB/sec
Maybe it's not completely fixed. I had to modprobe a bunch of stuff
manually before /dev/sda worked. Maybe hotplug isn't working?
Anyhow, the relative speed ratios explains the "pulsing" of /dev/hdb. My
laptop has a faster USB implementation I guess; AIR it was in the high 20
MB/s there.
