Algorithm is sha1. From printk, crypto_shash_descsize(tfm) comes out
to 0x60, digest_size to 0x14. Stack trace (for each modprobe [-r]) is 

	pkcs7_verify+0x1d0/0x5e0
	system_verify_data+0x54/0xb4
	mod_verify_sig+0xa0/0xc4
	load_module+0x48/0x16a0
	SyS_init_module+0x114/0x128
	linux_sparc_syscall+0x34/0x44
