Stock 1000HA (Seagate 5400.4, 1GB PC2-533). I removed the battery, and plugged the Eee PC into the Kill-A-Watt. The 802.11g was connected. For the LCD off test the Eee was plugged into a 17" LCD via a VGA cable.

Idle with the LCD off and ASUS Super Hybrid Engine set to auto was 10W.

The following test were run using Eeectl Low (1.0 GHz) and Turbo High (2.0 GHz) settings:

Code:
                 LCD off              LCD min              LCD max       
EIST Mhz     495/990  1010/2019   495/990  1010/2019   495/990  1010/2019
Idle          8.5     10.5         9.5     11.5        12.5     14.5
Orthos       10.5     14.5        --       --          --       --
ATI Tool     12       17.5        --       18.5        --       21.5
ATI + Orthos 12.5     18.5        13.5     19.5        16       22.5

Conclusions:

10" LCD uses 1W at minimum, 4W at maximum brightness.

The Atom N270 consumes at least 2W at 990 MHz and 6W at 2019 MHz. EIST idle at 1010 MHz consumes about the same power as running Orthos at 990 MHz.

3D Performance at 2019 MHz

909 points on 3Dmark03 at 1024x600 using the built in LCD. The game tests used 17W, but some of the feature tests used more power (20W). The original Half Life runs okay at 1280x1024 on the external monitor using 19W (internal LCD off.)

The Eee PC 1000HA is replacing my old mini-notebook, a NEC Mobile Pro 900C. The Eee PC is pretty power hungry comparison.

NEC Mobile Pro 900C
Intel XScale PX255 400MHz ~0.5W TDP
64MB RAM/64MB Flash
640x240 passive matrix touch screen
Microsoft Windows CE.NET 4.2

3W with display at minimum brightness
4W with display at maximum brightness

Popping in a 1GB compact flash card and overclocking the XScale to 530 MHz doesn't change the power numbers (One site said the XScale is <1W up to 800MHz.)

Some more idle power testing with removing and disabling components.

2GB Kingston ValueRAM 4-4-4-12

Normal 792MHz @ 1.013V Idle
10W LCD min, w/WiFi
9W LCD off, w/WiFi
8W LCD min
7W LCD off (no VGA)
6W LCD off, no HD

No Wifi + Disabled USB, LAN, Audio, Card Reader, and Camera in BIOS

Eeectl 495MHz @ 1.013V Idle
9W LCD min, w/WiFi + everything enabled
8W LCD off, w/WiFi + everything enabled
7W LCD min
6W LCD off
5W LCD off, no HD

So, the 802.11b/g card seems to use around 2W not doing much.
HD is around 1W
LCD is around 1W
