Hi,
According to Debian Linux HCL http://kmuto.jp/debian/hcl/Toshiba/T...dia+version%29 - your card has device ID 0x01da so it should be supported by NVDANV40HAL.kext (I can't make a profed statement for Leopard about this, as I am on Snow Leopard only)
First of all, I would recommend you not to use kext based device inject - this is an outdated method. Try to install latest PC_EFI Bootloader (v10.6) and add "GraphicsEnabler=Yes" bootflag to your com.apple.Boot.plist and see if this will enable QuartzExtreme support for you - once graphic accerlation is fully supported - we can see if we can manage to get your native resolution.
Last possible way might be to modify the VBIOS itself...  
AMD Phenom II X4 955 - ASRock AM3A770DE - 8GB DDR3-1333 - Radeon HD 5570 1GB passiv - BCM4318 802.11b/g - Snow Leopard Retail

AMD Phenom X3 8450 - ASRock AM2NF6G-VSTA (BIOS L2.39) - 4GB DDR2-800 - Radeon HD 4650 512MB - Snow Leopard Retail (retired) / OpenBSD
