EFI Partition Corrupt?

[cowfish]

I'm not sure if anyone does this any more with Lion, but I have my drive partitioned so that I have my kexts and DSDT on the EFI partition. My issue lately is that the EFI partition seems to be corrupt, but the system still works. It still boots fine and reads the partition during boot to load kexts, but when I'm in the OS I can't touch it. fsck tells me this:

 

 

Executing fsck_hfs (version diskdev_cmds-540.1~25).

Block 2 is not an MDB or Volume Header

Block 409598 is not an MDB or Volume Header

unknown volume type

primary MDB is at block 0 0x00

alternate MDB is at block 0 0x00

primary VHB is at block 0 0x00

alternate VHB is at block 0 0x00

sector size = 512 0x200

VolumeObject flags = 0x01

total sectors for volume = 409600 0x64000

total sectors for embedded volume = 0 0x00

CheckForClean - unknown volume type

 

As well is fdisk it show up like this:

 

1: EE 1023 254 63 - 1023 254 63 [ 1 - 409639] <Unknown ID>

 

I'm concerned that the superblock is bad or something but I'm not really sure what to do about this. I'd like to edit the partition, but I'm not desperate to do so since the system is still working fine. Any ideas on getting it mounted?
