Megaraid module won't detect logical disks on a CERC ATA100/4ch

[Matthew Schumacher <matt.s@aptalaska.net>]

I have had this problem for a while and it's still unresolved.

Linux fails to detect logical disks on any kernel past 2.4.27 which uses
the following driver:

Statistical Information for this controller
pend_cmds = 0
IO and error counters not compiled in driver.
root@jerry:/var/log# cat /proc/megaraid/hba0/config
v2.10.3 (Release Date: Thu Apr  8 16:16:05 EDT 2004)
CERC ATA100/4ch
Controller Type: 438/466/467/471/493/518/520/531/532
Controller Supports 40 Logical Drives
Controller capable of 64-bit memory addressing
Controller is not using 64-bit memory addressing
Base = f89c3000, Irq = 17, Initial Logical Drives = 1, Channels = 4
Version =6.62:1.03, DRAM = 16Mb
Controller Queue Depth = 254, Driver Queue Depth = 126
support_ext_cdb    = 1
support_random_del = 1
boot_ldrv_enabled  = 1
boot_ldrv          = 0
boot_pdrv_enabled  = 0
boot_pdrv_ch       = 0
boot_pdrv_tgt      = 0
quiescent          = 0
has_cluster        = 0

Module Parameters:
max_cmd_per_lun    = 63
max_sectors_per_io = 128

Every 2.4 kernel past 2.4.27 and every 2.6 kernel I have tried detect
the card, but not the disks.

Is this a known problem?  Any way around it?
