OK, I found a fix...of sorts. This is easier then the method described above. This page descibes how to uninstall the poorly designed Toshiba Bluetooth stack and reinstall the better designed Microsoft XP SP2 Bluetooth stack.

Once I followed the instructions to reinstall the XP SP2 bluetooth stack, the annoying bluetooth hardware disconnect everytime I went into standby went away.
I discourage anyone from installing the Toshiba Bluetooth stack on the i6000. I am sure it is the same for any laptop for that matter - but I only have experience with this issue on the i6000.
[Bluetooth Stack for Windows by Toshiba -> Microsoft Windows XP SP2 Stack]
CAUTION: Before performing any of the procedures detailed below, it's necessary to shut down the Bluetooth driver stack, as follows: Look in the Windows 'SysTray' (to the right of the Windows Task Bar, which is usually located at the bottom edge of the screen) for an icon in the form of either an antenna or a blue 'B'. If you see either one of these icons, right-click it, and then choose Exit – which will shut down the Bluetooth driver stack.
1. Download the install program "Bluetooth Monitor for MS stack Version 2.00" or later from the Toshiba WEB site. This does not actually install the Bluetooth Monitor for MS Stack, it places this readme on the system desktop and copies the installation executable to C:\Toshiba\BTMonitor\
(You can find the Toshiba Bluetooth Monitor for Microsoft WindowsXP XP2 here:

2. Open the Control Panel and uninstall "Bluetooth Stack for Windows by Toshiba", which is currently installed, then reboot your PC.
3. Run BTMON2INST.exe located in the folder c:\toshiba\BTmonitor to install the Bluetooth Monitor for MS Stack. Once installation is complete, restart the system to complete all changes.
4. "Microsoft Windows XP SP2 Stack" will be installed automatically. Open the Control Panel and open "Bluetooth Device" to configure the settings (to display the Bluetooth icon to the task bar, open "Options" tab and enable "Show the Bluetooth icon in the notification area").
Hope this helps someone.
