ThinkPad X40 with Ubuntu 10.04 (Lucid Lynx)

I’m writing this from Ubuntu 10.04 (Lucid Lynx) on my “travel” laptop, a venerable ThinkPad X40. There were two things I needed to fix to make it work:

The Intel Corporation 82852/855GM Integrated Graphics Device [PCI 8086:3582] needed Workaround A: Re-enable KMS found on Lucidi8xxFreezes to start X.

My Huawei E620 USB Modem [USB 12d1:1446/12d1:1001] for mobile broadband worked after removing the /etc/udev/rules.d/15-huawei-e1551.rules file I used to get the same device working in Ubuntu 9.10 (Karmic Koala).
