.kdfiles with boot start drivers on Vista

Anyone been able to use .kdfiles -m in WinDbg with boot start drivers on
Vista? After much wailing and gnashing of teeth I am thinking it can't be
done. Anyone?

I have seen some posts on this but they all either go no where or the people
replying didn't read very well.

Here is what I have tried. I tried using bcdedit to turn on the boot
debugger. Here is my output from WinDbg:

Waiting to reconnect...
BD: Boot Debugger Initialized
Connected to Windows Boot Debugger 6000 x86 compatible target, ptr64 FALSE
Kernel Debugger connection established.
Symbol search path is:

From the kd prompt I set >sxe ld:mydriver.sys and the debugger promptly
broke after all of the boot start drivers had been loaded?? The .kdfiles
mapping to my driver never kicked.

I am connecting WinDbg via NULL modem cable COM1 115200 baud.

I also tried loading a checked build of WinLoad.exe...still no love.

I can't seem to get the debugger to hook during boot.

HELP? Anyone? I have seen several veteran driver devs ask this same
question with no real help. If it isn't possible, it would be nice of
someone to just say so. In my case this would sure save me a ***-load of
time.

Thanks.
