Unless MS has changed the policy, The Windows 7 upgrade purchase is only valid for an equivalent level of Vista. See the "What are the "equivalent" Windows 7 products for Windows Vista?" below.
If I understand this correctly, you can't buy Windows 7 Home Premium upgrade and install it on Vista Basic.
But you can buy Vista Home Premium upgrade and load it on Vista Basic. Then after October 22, you'll get a free Windows 7 Home Premium upgrade that can be installed on Vista Home Premium.
Just be sure the Vista home premium upgrade you buy will come with the Windows 7 Home Premium upgrade on October 22. Seems there are some disclaimers that it's possible not all Vista Home premium upgrades will have the free Windows 7 upgrade option.
Hope this helps,

"Windows 7 Upgrade Option
How does the Windows 7 Upgrade Option work?
The Windows 7 Upgrade Option is available through participating PC manufacturers on selected PCs and through Microsoft on qualifying purchases of the Windows Vista packaged product. The Windows 7 Upgrade Option applies to Windows Vista Home Premium, Business, and Ultimate editions. Your Windows 7 upgrade will be to the comparable version: so you'll get either Windows 7 Home Premium, Windows 7 Professional (the upgrade to Windows Vista Business), or Windows 7 Ultimate, respectively. The Windows 7 Upgrade Option program runs from June 26, 2009 through January 31, 2010. Individual manufacturers may choose to offer the option for a shorter period on their PCs. Offer details, prices, and upgrade delivery methods will vary. For details for new PC purchases, please check the manufacturer's web site. For purchases of retail packaged software, please go to the Windows 7 Upgrade Option fulfillment site for retail packaged software.
What is the Windows 7 Upgrade Option program?
Specifically designated PCs that are pre-installed with Windows Vista Home Premium, Windows Vista Business, or Windows Vista Ultimate may qualify for an upgrade to the equivalent Windows 7 product. Similarly, in some markets, retail packaged Windows Vista software products (sold separately from PCs) may also qualify for an upgrade to the equivalent Windows 7 product. The upgrades will be provided to qualifying customers when the Windows 7 product becomes available on October 22, 2009.
