Looks like an old issue (even though I never experienced it before), but not quite fixed yet.
Logging on through ssh can easily take up to ~ 20 seconds even before the password prompt appears.

Comment out the following two lines in /etc/ssh/ssh_config and you should already see a noticeable improvement:
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no

Mounting a remote filesystem over SSH

Mainly applies to Ubuntu 9.04, but if you can get your hands on the package for another distribution / find the source package it'll probably work there too.

SSHFS is the package that'll work its magic for us. It's in the main repository nowadays so shouldn't be hard to find.
Else you can download it from here.

• Fire up the terminal and run "sudo apt-get install sshfs"
• Ensure you have a valid mount point available; I'd suggest something in your own userdir but it can be anywhere really. As long as your particular user has the appropriate rights.
• Run: sshfs remote_username@remote_host:/remote_path /local_path
(i.e.; "robert@myserver.com:/home/robert /home/robert/mnt/ssh" will log on to myserver.com as user 'robert', and mount the remote folder "/home/robert" to local folder "/home/robert/mnt/ssh")
• Accept any fingerprint warnings if you get them
• Done! The remote host is now mounted over SSH on your local box.

Broadcom BCM4328 under Ubuntu Jaunty

Apparently Ubuntu 9.04 doesn't support the Broadcom BCM4328 out-of-the-box (anymore);
• It shows up fine under "Hardware Drivers" as being enabled, though not in use
• No sign of WLAN in the connection manager

You now need to install another package to get it up and running again.
In order to get it working again;
• Install b43-fwcutter
• Disable/enable the driver through "Hardware Drivers" *
• Reboot.
* Optional step; might work without it but I didn't check. Takes 5 - 10 seconds anyway.

Note: the package above depends on several 3rd party (openwrt.org) packages, so you'll need to be connected to some kind of internet connection prior to installing it.

I've made a copy of these files, just in case:
b43-fwcutter_011-5_i386.deb
broadcom-wl-4.150.10.5.tar.bz2.tar
wl_apsta-3.130.20.0.o
