Well, you don't mention which bootloader you are using, or where your plist is located.

Different bootloaders may have different requirements for ordering of terms or location.

In case it helps, my /Extra/com.apple.Boot.plist is:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>Kernel</key>

<string>mach_kernel</string>

<key>Kernel Flags</key>

<string>arch=i386</string>

<key>GraphicsEnabler</key>

<string>No</string>

<key>Boot Banner</key>

<string>No</string>

<key>Legacy Logo</key>

<string>Yes</string>

<key>Timeout</key>

<string>5</string>

<key>Graphics Mode</key>

<string>1680x1050x32@60</string>

<key>VBIOS</key>

<string>Yes</string>

<key>DropSSDT</key>

<string>Yes</string>

<key>GeneratePStates</key>

<string>Yes</string>

<key>GenerateCStates</key>

<string>Yes</string>

</dict>

</plist>

I don't suggest that you copy it, but notice that 'Kernel' is first, followed by 'Kernel Flags'.

 

I would suggest removing the two sections:

 

<key>Kernel Architecture</key>

<string>i386</string>

 

<key>arch</key>

<string>i386</string>

 

and then moving the:

 

<key>Boot Graphics</key>

<string>Yes</string>

 

to after the Kernel Flags part.

 

Then make sure your plist is in the right place for your bootloader.
