The answer maybe yes for we have added the basic compressed kernel
support from 2.6.33:
arch/mips/boot/compressed/
but which board are you using? I just checked the arch/mips/Kconfig of
2.6.35 and only found the following boards enabled it:
config MACH_ALCHEMY
bool "Alchemy processor based machines"
select SYS_SUPPORTS_ZBOOT
config AR7
bool "Texas Instruments AR7"
[snip]
select SYS_SUPPORTS_ZBOOT_UART16550
config MACH_LOONGSON
bool "Loongson family of machines"
select SYS_SUPPORTS_ZBOOT_UART16550
config MIPS_MALTA
bool "MIPS Malta board"
[snip]
select SYS_SUPPORTS_ZBOOT

If your board are not related to any of the ones above, then, you may
need to select SYS_SUPPORTS_ZBOOT for your board and try it.
If it doesn't work, you may need to debug it with serial port or the
other methods. If your board have a 16550 compatible serial port, you
may be possible to select SYS_SUPPORTS_ZBOOT_UART16550 instead of
SYS_SUPPORTS_ZBOOT to enable the serial port debugging support, and at
last, to enable the serial port debugging output, you need to enable
CONFIG_DEBUG_ZBOOT.
You can get more help from arch/mips/boot/compressed/
BTW, to enable the zboot support, the bootloader of your board may
need the capability to parse the elf file.
