Hi,
Tested on Acer Aspire One A150 : MF636 with BT UK, yesterday's upgrade 
Karmic->Lucid:
- Booting without dongle :
  After inserting the dongle FIRST TIME AFTER BOOT : (timeline) (+next event 
duration) - times approximate
  - it gets recognized as CD ROM (BT AM), dmesg shows it is mass storage (+20s)
  - tries to mount the CD automatically, but dmesg shows it sees no media (+10s)
  - so it ejects CD (+10s)
  - then the dongle light goes off, (+10s), it turns on red (+5s) turns blue
  - dmesg shows mass storage device (MMC), and the usual 3 ttyUSB ports (+10s)
  - Network Manager recognizes the dongle, if was not configured, shows new 
option (behold, up to 2 minutes!)
  - (if connection configured) Network Manager shows twirling icon and connects 
(can take 30 seconds easily)
  - haven't done tests w/r/t stability of connection over long time though.
So from plugging in to getting internet connection it CAN take up to 4 minutes 
altogether.

When closed connection, unplugged the dongle, and plugged in again :
- it gets recognized as mass storage and dmesg is stuck on 'waiting for device 
to stabilize before scanning' (or so)
- gave up waiting after 2 minutes

If booting with dongle in the USB port : 
- it gets recognized as mass storage and dmesg is stuck on 'waiting for device 
to stabilize before scanning' (or so)
- gave up waiting after 2 minutes

But after poweroff/start up (haven't tried reboot only) it works through
the usual procedure, no problem until dongle unplugged.

(this is my boss's netbook, next time round it I will try to attach
dmesg of both cases)
