For the sake of completeness: Detonator 26.25/26.53
After a number of leaked 27.xx versions of the nVidia Detonator drivers, MaxReboot.com has now also offered the versions 26.25 and 26.53 from WindowsUpdate.com for download. Unlike the 'NV17 only' 27.00 WHQL widespread there, these versions work with every current nVidia graphics card.
However, owners of Windows 9X/Me look into the tube. The drivers are only available for the Windows 2000 and XP operating systems.
