Both Compaq's Presario 2800 and EVO N800 series, are build with a Radeon Mobility 7500. However, Compaq gives no support in Windows 2000 for this card, on Presario 2800 series, because they are sold only with Windows XP.
But the EVO N800 series, comes with an option of Windows 2000, and there Compaq delivers a compliant display driver.
So, the display driver available by Compaq to the EVO N800 series, running Windows 2000, also works on Presario 2800 series running Windows 2000.
