delphicgp,
no it is not the case.
I had some time to create a design with CFI flash and SDRAM and I put the reset vector to the cfi_flash and i was able to test this flash using Altera memtest.
The proof:
Select Choice (a-b):
b
Enter the name of the CFI flash device to be opened,
or just press <enter> to open "/dev/ext_flash"
>
/dev/cfi_flash
-Successfully opened /dev/cfi_flash
-Region 0 contains 8 blocks.
-Checking Region 0 for erased blocks.
-Block 1, at address 0x2000 identified.
-Would you like to test this block? (y/n)
y
-Starting Flash Test.
-Testing "alt_write_flash" and "alt_read_flash".
pass 1 - passed.
pass 2 - passed.
-Testing "alt_erase_flash_block". passed.
-Testing "alt_write_flash_block". passed.
-Testing unaligned writes. passed.
-Returning block 1 to its erased state.
-Flash tests complete.
-Closing flash device "/dev/cfi_flash".
I use Terasic DE0 board as a hardware - you can check on their website how flash is connected.

Thanks for your reply!!!
I have never successfully open my CFI flash when I run memtest.
Do you know why?
