GiveIO.sys on Win7-64

Hi,
I have an old project using GiveIO.sys to use IO under XP.
Now I got an X64 system with w7-64 on it, the driver won't load.

Is there a 64 Bit version of GiveIO.sys ?
I see a lot of questions on inet, but no answers.
Is it technically possible to use the same "trick" giveio.sys uses under XP, under win7-64 ?
With giveio.sys comes giveio.C , but unfortunately, no project to build it with...

Is it impossible to run a 32 bit driver under win7-64 ? or just blocked for safety/compatibility reasons ?
