I've just found in LDD 2nd version book (page 218), that on MIPS, 
addresses returned by vmalloc belong to a completely different address 
range from kmalloc addresses, whereas on x86 platforms they belong to 
the same.

Concerning the clues given by Ralf, I've tried insmoding the module by a 
recent version of modutils instead of using the insmod brought with 
Busybox : the kernel behaved the same, it doesn't want to use the 
handler of my kernel.
I've also checked that I was compiling with the mlong-calls flag...

Therefore, I think I will compile my module into the kernel, until I 
found a solution to this problem...

Thanks everyone!
