Short overview (for news sites, etc)
Linux 2.6.20 greatly improves kdump (http://news.zdnet.co.uk/software/0,1000000121,39285165,00.htm ); KVM (http://kvm.sourceforge.net) for Intel with VT and AMD with SVM hardware virtualization; Support for relocatable kernels, for backups with kernel panics.
Important things (AKA: ''the cool stuff'')

Drivers
- Removal of the crusty FTape driver
- Add support for Moxa SmartIO multiport serial cards
- New Winbond W83793 hardware monitoring driver
- ohci1394: steps to implement suspend/resume
- allow usb hubs to have up to 31 children
Network
- Atmel MACB support
Add NetXen 1G/10G ethernet driver.
- e1000: New hardware support
- forcedeth: power management support
PATA
- Add support for Winbond, Marvel, and others

Other stuff
Arch-independent changes in the kernel core
Add support for Log2 mechanism [http://lwn.net/Articles/203596/]
Driver core: add notification of bus events [http://lkml.org/lkml/2006/12/1/297]
